## Release decisions and open reviews

### Troodon · answer identity

For daily answers, follow the 2025 Troodon genus concept or retain Stenonychosaurus as the canonical skeleton-based name?

Approved decision: Use the published 2025 Troodon framework. Troodon is the canonical hidden answer; Stenonychosaurus and Latenivenatrix remain legal equivalent winning guesses. Preserve all three source identities and fossil records separately. This is a chosen published framework, not universal consensus.

Evidence: [Troodontid specimens from the Cretaceous Two Medicine Formation of Montana (USA) and the validity of Troodon formosus](https://www.cambridge.org/core/journals/journal-of-paleontology/article/troodontid-specimens-from-the-cretaceous-two-medicine-formation-of-montana-usa-and-the-validity-of-troodon-formosus/3E58F1FDA3FE53DE569E0D0B20E79F22); [Troodontids from the Dinosaur Park Formation, Alberta, with a description of a unique new taxon: implications for deinonychosaur diversity in North America](https://doi.org/10.1139/cjes-2017-0031); [Diet of bird-like troodontid dinosaurs: synthesis of a contentious clade](https://www.researchgate.net/publication/400784396_Diet_of_bird-like_troodontid_dinosaurs_synthesis_of_a_contentious_clade); [Dinevenator, a New Genus of Troodontid Dinosaur from the Late Cretaceous of New Mexico](https://www.researchgate.net/publication/411150348_Dinevenator_a_New_Genus_of_Troodontid_Dinosaur_from_the_Late_Cretaceous_of_New_Mexico)

### Alcovasaurus · answer identity

Keep Alcovasaurus as a separate daily-answer genus under the 2025/2026 Dacentrurus framework, or adopt Costa 2026 Miragaia and use Alcovasaurus only as a legal historical guess?

Approved decision: Retain Alcovasaurus as a legal guess, with an independent hidden-answer hold while the genus-level identity remains unresolved.

Evidence: [Dacentrurine Stegosaurs in North America: New Occurrences from the Upper Jurassic of USA (Morrison Formation)](https://dinodata.de/bibliothek/pdf_d/2026/diversity-18-00143_dd.pdf); [The plated dinosaurs (Ornithischia, Stegosauria) of eastern Iberia (Spain): Taxonomy, diversity, and ecology](https://www.palaeo-electronica.org/content/2026/5818-stegosaurs-of-eastern-iberia); [Dacentrurine stegosaurs: a new specimen of Miragaia longicollum from the Late Jurassic of Portugal resolves taxonomical validity and shows the occurrence of the clade in North America](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0224263)

### New genera outside the frozen baseline · Cryptarcus and Dinevenator

Refresh the captured PBDB baseline to assess newly described Cryptarcus and Dinevenator, or keep these outside this version until the next source refresh?

Approved decision: Wait for an explicit, verified PBDB baseline refresh before admitting Cryptarcus or Dinevenator. Capture source identities and specimen-specific mappings; do not invent IDs.

Evidence: [Holmes, Mallon, Ryan & Evans (2026), New information on the holotype of Chasmosaurus russelli necessitates the establishment of a new genus](https://doi.org/10.1139/cjes-2025-0031); [Jasinski and Sullivan 2026 · Dinevenator, a New Genus of Troodontid Dinosaur from the Late Cretaceous of New Mexico](https://doi.org/10.3390/fossils4030021)

### Alwalkeria · dinosaur scope

Keep the PBDB-selected guess while the revised name-bearing femur is Pan-Aves incertae sedis, or remove it from the dinosaur roster under the newer specimen-based treatment?

Approved decision: Exclude Alwalkeria from the dinosaur roster under the revised treatment of its name-bearing material. Preserve the source record and reconsideration condition.

Evidence: [Taxonomic reassessment of archosaurs with dinosaurian affinities from the lower fauna of the Upper Triassic Maleri Formation of India and their significance](https://www.tandfonline.com/doi/abs/10.1080/02724634.2025.2546434); [Alickmeron Sen & Ray, 2025 is an objective junior synonym of Alwalkeria Chatterjee & Creisler, 1994](https://www.tandfonline.com/doi/full/10.1080/02724634.2025.2604088)

### Saltopus inclusion review

The dedicated revision places Saltopus outside Dinosauria. Retained as a provisional PBDB legal guess pending exclusion review; administrative root attachment is not dinosaur membership.

Approved decision: Exclude from the dinosaur roster.

Evidence: [Saltopus, a dinosauriform from the Upper Triassic of Scotland](https://doi.org/10.1017/S1755691011020081)

### Protoavis inclusion review

Probably composite name-bearing material does not establish one diagnosable dinosaur genus. Retained guess; no independent hidden answer or unsupported finer ancestry.

Approved decision: Exclude unless an independently diagnostic name-bearing dinosaur identity can be supported.

Evidence: [A critical re-evaluation of the Late Triassic dinosaur taxa of North America](https://doi.org/10.1017/S1477201906002040)

### Yaverlandia inclusion review

The 2026 dedicated revision leaves dinosaur identity unresolved; no supported maniraptoran, pachycephalosaur or other narrow branch.

Approved decision: Keep on hold; exclude from the active dinosaur roster pending secure identity.

Evidence: [A second specimen of the enigmatic Wealden reptile Yaverlandia](https://doi.org/10.1016/j.pgeola.2026.101179)

### Krzyzanowskisaurus inclusion review

Tooth-based identity may belong to Revueltosaurus or another non-dinosaurian archosaur; an ornithischian branch is unsupported.

Approved decision: Exclude pending secure dinosaur identity.

Evidence: [The first occurrence of the enigmatic archosaur Krzyzanowskisaurus hunti in Arizona](https://pmc.ncbi.nlm.nih.gov/articles/PMC4411520/); [Fonseca et al. 2024: Supplementary Data 1, excluded and fragmentary taxa](https://doi.org/10.6084/m9.figshare.26076646)

### Ferganocephale inclusion review

Dubious tooth-based name; only a broad Saphornithischia interpretation is defensible, without a diagnosable independent hidden answer.

Approved decision: Exclude until diagnostic material supports this name.

Evidence: [Fonseca et al. 2024: Supplementary Data 1, excluded and fragmentary taxa](https://doi.org/10.6084/m9.figshare.26076646)

### Gongbusaurus inclusion review

The dubious tooth-based type shiyii does not inherit the more informative ancestry of referred wucaiwanensis material.

Approved decision: Exclude the type-based genus pending diagnostic revision.

Evidence: [Fonseca et al. 2024: Supplementary Data 1, excluded and fragmentary taxa](https://doi.org/10.6084/m9.figshare.26076646)

### Nanosaurus inclusion review

The dedicated 2025 revision finds the name-bearing material indeterminate; historical referred skeletons cannot establish an independent answer.

Approved decision: Exclude until a diagnostic name-bearing identity is supported.

Evidence: [A Review of Nanosaurus agilis Marsh and Other Small-Bodied Morrison Formation Ornithopods](https://doi.org/10.3374/014.066.0102)

### Stormbergia inclusion review

Chosen literature treats Stormbergia as a junior subjective synonym of Lesothosaurus; keep the PBDB guess distinct pending the inclusion decision.

Approved decision: Retain Stormbergia as an accepted equivalent of Lesothosaurus. It solves a hidden Lesothosaurus and records the canonical Lesothosaurus discovery; there is no separate Stormbergia answer.

Evidence: [The postcranial anatomy of Lesothosaurus diagnosticus: implications for basal ornithischian taxonomy and systematics](https://doi.org/10.1111/zoj.12434); [A comprehensive phylogenetic analysis on early ornithischian evolution](https://doi.org/10.1080/14772019.2024.2346577)

### Serendipaceratops inclusion review

Fragmentary type and conflicting ceratopsian, ankylosaurian and indeterminate ornithischian interpretations support only Genasauria.

Approved decision: Retain as a broad Genasauria legal guess with an independent hidden-answer hold.

Evidence: [Fonseca et al. 2024: Supplementary Data 1, excluded and fragmentary taxa](https://doi.org/10.6084/m9.figshare.26076646); [An annotated checklist of Australian dinosaurs](https://doi.org/10.1080/03115518.2023.2228367)

### Notoceratops inclusion review

Lost, fragmentary type and conflicting ceratopsian/hadrosaur interpretations do not support a dependable narrow working branch.

Approved decision: Retain as a broad Genasauria legal guess with an independent hidden-answer hold.

Evidence: [Fonseca et al. 2024: Supplementary Data 1, excluded and fragmentary taxa](https://doi.org/10.6084/m9.figshare.26076646)

## What this pass decided

- 47 source identities excluded under explicit, approved identity/scope exceptions. Every exclusion below has an individual rationale, sources in the export, and a recorded reconsideration condition.
- Retain disputed but potentially defensible PBDB genera as guesses; separate independent hidden-answer eligibility. No automatic transfer of a composite fossil assemblage to another genus.
- Correct erroneous parents and use broader published common ancestors where fine placements conflict. 692 working paths differ from the source, including the declared Saurischia backbone; this is not a count of database errors.
- Fill diet gaps using referenced anatomy or supported relatives. Animal and mixed/plant interpretations remain compatible where disputed. Nine profiles still lack a defensible diet clue and stay out of the answer pool.
- Map the 57 affected Russia/Kazakhstan/offshore occurrence records from collection context; fill supported broad period and region gaps without manufacturing occurrence IDs.
- Preserve qualified referrals and alternate horizons, including Conchoraptor’s possible Nemegt record and Peloroplites’ conflicting member label. Add positive referred localities for Minotaurasaurus and Dzharacursor without assigning them to an unknown type quarry.
- Screen every eligible profile against its blind sibling group using overlapping diet, period and geography interpretations. 451 profiles receive sourced free locality support; no screened group remains above five.
- Correct displayed generic attributions for Coloradisaurus, Riabininohadros and Nipponopelta while preserving the captured attribution separately.
- Keep the frozen baseline stable. Newly described Cryptarcus and Dinevenator are explicit refresh leads rather than invented PBDB entries. Dinevenator is distinct from the selected Dineobellator.
- Expert mode uses this roster for daily and practice expeditions. The original 36-genus sample and its saved rounds remain separate.

## Answer holds

| Genus | Reason |
| --- | --- |
| Agnosphitys | No defensible diet clue is currently supported. |
| Alcovasaurus | Costa 2026 treats longispinus as Miragaia, while March 2026 Sánchez-Fenollosa et al. endorse Miragaia longicollum within Dacentrurus and explicitly do not support Alcovasaurus–Dacentrurus synonymy. There is no single uncontested latest generic scheme. |
| Balochisaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Bravoceratops | Conflicting current assessments of independent diagnosability. |
| Coelurus | No defensible diet clue is currently supported. |
| Epidendrosaurus | Primary review treats Scansoriopteryx as the same taxon and discusses competing priority interpretation. An electronic/print publication argument is not a discovered ICZN ruling. Epidendrosaurus is a defensible current usage label but formal precedence must not be overstated. |
| Epidexipteryx | Cau 2024 tentatively combines Epidexipteryx and Epidendrosaurus in one OTU, interpreting differences through growth and incomplete preservation. This is a live proposal rather than settled consensus; a roster cut or wholesale specimen merger is not justified by this source alone. |
| Euskelesaurus | PBDB 81225 is placed in Stegosauria with no occurrences; historical spelling points to Euskelosaurus, a Triassic sauropodomorph. Do not merge or fix inherited diet until source identity is verified.; No defensible period clue is currently supported.; No defensible geography clue is currently supported. |
| Geminiraptor | September2026 primary revision recombines the species as Falcarius suarezarum; no independent duplicate hidden answer. |
| Gspsaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Hanssuesia | The 2023 comparative and morphometric revision interprets Hanssuesia and Gravitholus within Stegoceras validum ontogeny and dimorphism. Keep the PBDB identity as a legal guess under the parent policy, with no separate daily answer. |
| Ikqaumishan | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Imrankhanhero | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Khanazeem | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Khetranisaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Kol | No defensible diet clue is currently supported. |
| Latenivenatrix | 2021 synonymy with Stenonychosaurus is followed by the 2025 revision; 2026 papers still acknowledge uncertainty. Merely scoring it as a separate matrix OTU is not revalidation. |
| Marisaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Mirischia | No defensible diet clue is currently supported. |
| Nedcolbertia | No defensible diet clue is currently supported. |
| Nicksaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Notoceratops | Lost, fragmentary type and conflicting ceratopsian/hadrosaur interpretations do not support a dependable narrow working branch. Approved treatment: retained as a broad legal guess with an independent hidden-answer hold. |
| Nyasasaurus | Dinosaur versus near-dinosaur status remains unresolved. The administrative root attachment must not be interpreted as secure membership of either main branch.; No defensible diet clue is currently supported. |
| Pakisaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Qaikshaheen | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Qijianglong | Jurassic versus Cretaceous interpretation is not settled by direct type-quarry evidence. |
| Santanaraptor | No defensible diet clue is currently supported. |
| Saraikimasoom | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Scansoriopteryx | Synonymy with Epidendrosaurus has a published basis; priority discussions disagree over electronic versus printed availability. Type age and locality are not securely solved by spelling choice. |
| Serendipaceratops | Fragmentary type and conflicting ceratopsian, ankylosaurian and indeterminate ornithischian interpretations support only Genasauria. Approved treatment: retained as a broad legal guess with an independent hidden-answer hold. |
| Stenonychosaurus | 2017 resurrected the genus; 2025 regards it as a junior synonym of Troodon. Do not make Troodon and Stenonychosaurus separate daily answers for the same adopted species concept. |
| Stormbergia | Approved junior-synonym treatment: Stormbergia is an accepted equivalent guess for Lesothosaurus, not a separate hidden answer. |
| Sulaimanisaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Tanycolagreus | No defensible diet clue is currently supported. |
| Vitakridrinda | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Vitakrisaurus | Later papers supply diagnoses, designated types and locality statements; old conference-name dates alone do not justify a nomen nudum cut. Independent diagnosability and specimen associations remain insufficiently verified for hidden answers. |
| Xinjiangovenator | No defensible diet clue is currently supported. |
| Zigongosaurus | Composite material, the doubtful original species record and catalog-number concordance do not yet support a coherent independent answer. |

## Exclusions

| Source name / ID | Decision |
| --- | --- |
| Saurornithoides / 69227 | Use Saurornithoides Osborn 1924 (PBDB 38573), the troodontid genus treated in the published taxonomic review. Hold the same-name Nopcsa 1928 record (PBDB 69227) out of the expanded roster for nomenclatural review. This is an explicit identity selection, not a merger of records or their occurrence evidence. |
| Ancistrodon / 154360 | PBDB 154360 is attributed to Huxley 1865 and placed directly under Dinosauria, but its only captured occurrence 434618 is Ancistrodon libycus from the Ypresian of Saudi Arabia. Priem treats that species name among fossil fish. Modern work treats Huxley’s Ankistrodon indicus as an Early Triassic proterosuchid archosauriform. The record appears to combine distinct historical names; the exact database repair is unresolved. |
| Shuuvuia / 307772 | Use only Shuvuuia (66043). Both PBDB spellings cite the same original description; primary systematic treatment and spelling-correction opinions support one genus. The user approved this explicit identity exception. Hold Shuuvuia (307772) out as a duplicate spelling identity, without transferring occurrence evidence or ancestry. |
| Hylosaurus / 66560 | Use Hylaeosaurus (38822). The Hylosaurus record (66560) has the same Mantell 1833 attribution and original reference, no linked occurrences or child species, and a selected opinion explicitly marked misspelling. This is an approved spelling-identity hold; distinguish the database Mantell record from Fitzinger’s later Hylosaurus mantelli, treated as a nomen nudum by Raven. Preserve both records without transferring fossil evidence or ancestry. |
| Hoplosaurus / 53046 | Retain Struthiosaurus (38830); hold Hoplosaurus Seeley 1881 (53046) out as a separate genus. The Dinosauria distribution chapter (2004) includes Hoplosaurus ischyrus within Struthiosaurus austriacus. PBDB still accepts Hoplosaurus and also attaches older Pelorosaurus synonymy opinions apparently involving a separate sauropod spelling usage. The full 2001 taxonomic reappraisal has not been inspected; do not assert a completed formal synonymy or database repair. This approved hold does not merge fossils, names or ancestry. |
| Eosauropoda / 370667 | PBDB 370667 self-accepts Eosauropoda Bonaparte 1986 at genus rank. The cited original publication instead treats Eosauropoda as a suprageneric grouping containing named genera. Exclude this rank-mismatched identity from guesses and answers. Preserve the source record; no genus, occurrence or ancestry transfer, and no new working-tree group is introduced. |
| Nemegtia / 68043 | Use Nemegtomaia (95490) as the single dinosaur genus identity. Lü et al. 2005 formally replaced Nemegtia Lü et al. 2004 because that name was preoccupied by an ostracod. PBDB separately accepts the empty Nemegtia record (68043), but already links the original type occurrence to Nemegtomaia. Hold the former-name identity out of independent guesses and answers. Preserve all three canonical occurrences and the supported Nemegt and Baruungoyot profiles, including unresolved specimen-level horizon uncertainty. No occurrence transfer or ancestry amendment is introduced. |
| Eucentrosaurus / 94334 | Replacement name for the same nominal type species already represented by Centrosaurus; no independent answer animal. |
| Proiguanodon / 383092 | Original source uses this as a grouping within Iguanodon, not a separate described genus. It includes more than one later genus, so a single genus alias would be misleading. |
| Proyandusaurus / 435994 | Both publications expressly identify the same nominal Yandusaurus multidens species; this is not evidence for a second fossil animal. |
| Nectosaurus / 382945 | This is the1910 dinosaur usage for Brown’s navajovius skull, not marine Nectosaurus Merriam1905. PBDB itself records the usage as a recombination of the accepted Kritosaurus navajovius species. |
| Galveosaurus / 67715 | Both names denote the same holotype CLH-16. Galvesaurus is used by 2012/2019/2024 revisions and has the richer PBDB record, but priority dispute remains disclosed, not judicially resolved. |
| Microsaurops / 83019 | Published revision1991 treats it as a spelling/replacement artifact under Microcoelus, not an independently described animal. |
| Dachongosaurus / 313245 | Explicit nomen nudum for Dachungosaurus, with Dachongosaurus alternative spelling. Revision states remains undescribed although an in-situ photograph was published. A photographed skeleton alone is not an independently diagnosed genus. |
| Oshanosaurus / 313242 | Explicit nomen nudum. Revision states remains undescribed and appears in a faunal list. No later formal validation found. Do not assume Eshanosaurus synonymy or automatically redirect. |
| Damalasaurus / 313240 | Explicit nomen nudum. Historical magnus/laticostalis usages do not establish available independently diagnosed genus. Zhao1983 p302 mentions Damalosaurus only as evolutionary example. Geographic disambiguation does not repair nomenclatural availability. |
| Microdontosaurus / 65648 | Explicit nomen nudum. Zhao1983 p304 provides only a brief evolutionary example. Geographic and Chaya locality data do not establish nomenclatural availability. |
| Ponerosteus / 92286 | Olshevsky 2000 naming-author statement calls the genus and species nomina dubia and doubtfully dinosaurian. A specimen which cannot securely establish even dinosaur affinity or an independently diagnosable genus is unsuitable as a separate playable genus. |
| Xuanhuasaurus / 313238 | Zhao et al. 2006 p467 explicitly labels the earlier Xuanhuasaurus niei nomen dubium while stating no holotype, diagnosis or description was provided. Olshevsky 1991 p159 labels Xuanhuasaurus nomen nudum. An undescribed historical name for the material later formally described as Xuanhuaceratops; retained in the history, not counted as a separate playable genus. |
| Actiosaurus / 268200 | Type reassessment calls the species inquirenda and identifies possible choristodere propodials, not a demonstrated dinosaur. |
| Alwalkeria / 66343 | 2025 reassessment assigned the type-associated femur to Lagerpetidae and introduced Alickmeron; 2026 correction makes Alickmeron an objective junior synonym of Alwalkeria. Original assemblage is heterogeneous. |
| Avalonianus / 56608 | The name-bearing tooth material is indeterminate archosaurian; historically associated postcranium does not diagnose this genus and relates to Camelotia. |
| Bagaraatan / 57248 | The 2024 redescription partitions the original skeleton into a juvenile indeterminate tyrannosaurid type and caenagnathid hindlimb elements. Alleged diagnostic type features may be ontogenetic or individual variation; no supported automatic Tarbosaurus/Alioramus alias follows. |
| Changdusaurus / 65646 | Historical Changtusaurus/Changdusaurus draft-name spellings; no formal genus description found. |
| Coloradia / 38639 | Preoccupied by the moth genus; retained Coloradisaurus is the replacement. |
| Eugongbusaurus / 435996 | The 1999 abstract proposes this new genus without a qualifying generic differential description or reference to one; unavailability is an Article 13.1 inference. Type fixation through monotypy is not the asserted defect. |
| Fenestrosaurus / 65168 | Informal preliminary name of Oviraptor, not an additional animal. |
| Himeoolithus / 450385 | Explicitly an egg oogenus, not an independently identified body genus. |
| Ingenia / 38560 | Ingenia Barsbold 1981 is preoccupied by the nematode genus Ingenia Gerlach 1957; replacement Ajancingenia later becomes a subjective synonym of Heyuannia in the adopted revision. |
| Koutalisaurus / 91407 | The supposed distinctive symphyseal projection on IPS 29920 was partly preparation infill. The 2013 revision identifies the cleaned dentary as indeterminate Lambeosaurinae and explicitly cannot refer it to Pararhabdodon. The 2021 Ajnabia matrix does not rebut this diagnostic failure. |
| Ngexisaurus / 66640 | Zhao lists this name but provides no qualifying individual diagnosis or type fixation; no subsequent formal description located. |
| Ornithomimidorum / 66988 | Provisional Latin grouping phrase, not an independently erected genus; B later became Betasuchus. Do not alias the entire A/B grouping to one genus. |
| Ovoraptor / 65172 | Informal preliminary name of Velociraptor. |
| Priodontosaurus / 105576 | Catalogued incorrect spelling of Priodontognathus. Canonical genus is absent from current selected set; do not create an alias to a nonexistent game target. |
| Sangonghesaurus / 66638 | Listed without a type species or qualifying original description. Do not infer synonymy with Tianchisaurus. |
| Sauraechmodon / 168391 | Unused historical name for Echinodon, not an independently diagnosed animal. Exact nomenclatural availability need not be asserted for this duplicate-slot exclusion. |
| Saurophaganax / 65370 | The 2024 revision finds holotype OMNH 1123 unidentifiable as a diagnostic theropod and probably sauropod in morphology. Saurophaganax is not simply renamed Allosaurus anax; only particular formerly referred specimens support the new species. |
| Sauropus / 67050 | Footprint ichnogenus; revised type is indeterminate worn track material. |
| Syntarsus / 38525 | The dinosaur generic name is preoccupied by Syntarsus Fairmaire 1869. Unqualified Syntarsus is also ambiguous between rhodesiensis and kayentakatae. Do not redirect every Syntarsus guess to Megapnosaurus. |
| Yezosaurus / 169801 | Informal name for mosasaur MCM.M0009, described in 2008 as Taniwhasaurus mikasaensis and subsequently treated as Taniwhasaurus sp.; no independent dinosaur identity. |
| Saltopus / 38518 | The dedicated revision places Saltopus outside Dinosauria. |
| Protoavis / 192928 | Probably composite name-bearing material does not establish one diagnosable dinosaur genus. |
| Yaverlandia / 38792 | The 2026 dedicated revision leaves dinosaur identity unresolved; no supported maniraptoran, pachycephalosaur or other narrow branch. |
| Krzyzanowskisaurus / 105061 | Tooth-based identity may belong to Revueltosaurus or another non-dinosaurian archosaur; an ornithischian branch is unsupported. |
| Ferganocephale / 64059 | Dubious tooth-based name; only a broad Saphornithischia interpretation is defensible, without a diagnosable independent hidden answer. |
| Gongbusaurus / 38719 | The dubious tooth-based type shiyii does not inherit the more informative ancestry of referred wucaiwanensis material. |
| Nanosaurus / 38738 | The dedicated 2025 revision finds the name-bearing material indeterminate; historical referred skeletons cannot establish an independent answer. |
