# Locality Survey — 10 October 2026 Every large source group was screened. This is a complete database pass, not an exhaustive specimen-level literature review or hidden-answer approval. Coverage: 108 large direct-parent groups / 997 genera; 63 matching pools / 484 provisional genera; 6285 frozen occurrence rows; 4016 linked collections, none missing. Potential splits: formation alone for every target in 51 pools; any tested place field for every target in 62. 5 targets in 1 pools still lack a source-screen sub-five split. These figures cannot certify fair elimination from a non-exhaustive catalogue. ## Overlap rule - Every matching pool and every direct-parent group with at least five selected genera is screened. These are provisional candidates, not certified viable hidden answers. - Every frozen linked occurrence contributes. A genus matching ANY occurrence of an anchor is retained, irrespective of its preferred or type locality. - Qualified cf., aff. and ? occurrences remain plausible overlaps; their uncertainty is reported rather than used to eliminate a candidate. - Genera with no usable locality evidence, or relevant missing metadata, remain possible. Positive literature supplements are identified separately; catalogue non-matches are provisional, never proof that a dinosaur was absent from a place. - Country and stratigraphic rank are part of an anchor. Members require a formation context; counties require a state context. Place names and formation names are never conflated. - Whitespace/case/Unicode, surrounding quotation marks and rank suffixes are normalized. Cited, country- and rank-scoped aliases and the broad Shaximiao hierarchy are applied as a review overlay; other synonyms and renamings remain unresolved. - Counts precede guesses. A five-genus footprint can leave four after guessing one of its members; the runtime must recompute after every guess. - Cited exact-record corrections apply to a separate reviewed catalogue; original frozen rows remain available. Conflicting supported horizons are retained as alternatives. Broad summaries linked to existing records do not manufacture new unknown-horizon fossils. - A collection ID is a database record, not an exclusive physical dig site. Quarry/site clues need reviewed site identities and aliases; separate collection IDs cannot eliminate genera. - No original discovery or holotype locality is inferred from oldest publication, record order or collection name. Type anchors need the original description or a specimen-level revision. - Screened sub-five splits require scientific validation before use. A preferred discovery anchor controls wording, never the membership filter. - The live 36-genus roster and daily eligibility are unchanged. ## Every matching-clue pool | Parent | Standard clues | Genera | Formation split targets | Any place split targets | Unresolved targets | | --- | --- | ---: | ---: | ---: | --- | | Hadrosauroidea | herbivore · Cretaceous · Asia | 24 | 21 | 24 | None in screen;

Fresh primary evidence can expose stale occurrence assignments even in recent PBDB snapshot. Flag; do not silently rewrite roster. - Bravoceratops: Fowler2020 questions diagnostic validity/reconstruction; roster inclusion follows PBDB but hidden-answer/locality approval still requires reviewed material. - Torosaurus, Triceratops: Competing ontogenetic synonymy hypotheses do not remove geographic overlap.

Do not merge all southern Chinese basins or assign all heyuanines to Nanxiong on reputation. - Hekou Group, Xiagou Formation, Xinminpu Group: Gansu geography alone cannot merge these stratigraphic units. - Full referred-specimen ranges and revised taxonomic assignments for all members, beyond positive overlaps above. - Heyuannia/Ingenia historical generic identities and species combinations before attaching multi-species geography. - Conchoraptor possible Nemegt records versus secure Barun Goyot records; original detailed provenance review not completed here. - Shixinggia, Heyuannia and Jiangxisaurus precise stratigraphic units and Nanxiong Group/Formation usage, rather than treating South China as one unit. - Oksoko inferred provenance must not supply a confident type-discovery quarry. - Qijianglong's reported Suining versus Upper Shaximiao provenance dispute. - Zigongosaurus/Mamenchisaurus scientific synonym issues before using a five-genus Shaximiao count as five independently guessable animals. - Direct PBDB parent pools are diagnostics, not necessarily the full descendant candidate universe used by gameplay. - Peloroplites: 2026 Table 1 reports CEUM 34580 from Ruby Ranch while the original PR-2 description gives Mussentuchit. Preserve both contexts; verify tooth/site association before claiming a unique genus-wide member range. Phylogenetic placements also vary; no tree change is approved by this locality pass. - Daxiatitan, Yongjinglong: Retain Hekou as a geological group; clear the misleading formation values Upper and 5 in the reviewed copies only. Bind the existing literature summary to the actual Gansu occurrence rows, without adding unknown-province duplicate fossils. - Lingwulong: Fill the missing reviewed formation with Yanan for the Lingwu Geopark occurrence; retain Ningxia geography and the broad published age interval. - Ganzhousaurus, Jiangxisaurus, Nankangia: Fill formation-rank Nanxiong on the individually matched original-description rows, retaining their raw group fields. Bind broad group summaries to existing rows. Do not equate their proxy collection numbers with a shared quarry. - Banji: Retain possible Nanxiong provenance as uncertain evidence, not an exact quarry or a certain exclusive formation. Bind the existing broader summary to its Jiangxi source row. - Liubangosaurus, Fusuisaurus: Document Xinlong as the preferred formation name and Napai/Napan as older names for these Guangxi red beds. Retain both named sauropods at Liubang; a quarry clue must include both. - Jiangshanosaurus, Dongyangosaurus: Keep documented Jinhua/Zhejiang locality profiles and early Late Cretaceous interpretation; do not apply a global Fangyan-to-Jinhua alias or a convenient tree placement. - Erketu: Flag the Chinese row as an unconfirmed genus referral and retain it conservatively in comparisons. Do not erase China from its footprint or claim a verified Chinese Erketu discovery. - Qingxiusaurus: Use the published Guangxi/Nanning red-bed context without inventing a named formation from the Nalong Basin name. - Xuanhuasaurus, Damalasaurus, Microdontosaurus, Dachongosaurus, Oshanosaurus, Ponerosteus, Hanssuesia, Isanosaurus: Retain PBDB guesses; hidden-answer readiness remains pending original identity, material, date or complete clue evidence as individually specified. - Abrosaurus, Daanosaurus, Omeisaurus, Qijianglong, Zigongosaurus: Refine confirmed Lower/Upper occurrences; retain the Qijianglong conflict and genus-wide Omeisaurus range. Do not pretend five names establish five independent animals. - Abrosaurus, Daanosaurus, Dashanpusaurus, Datousaurus, Omeisaurus, Protognathosaurus, Qijianglong, Shunosaurus, Yuzhoulong, Zigongosaurus: Use honest member/site information where known; shared Lower Shaximiao quarries are genuine overlap and require free help if they remain an indistinguishable five-plus state. - Bisticeratops, Navajoceratops, Pentaceratops, Terminocavus, Titanoceratops, Torosaurus: Retain qualified Fruitland/Kirtland identities and Naashoibito’s alternative naming schemes; use member information without erasing unknown or referred material. - Bonitasaura, Inawentu, Neuquensaurus, Overosaurus, Rinconsaurus, Traukutitan, Yeneen: Keep the seven-genus formation overlap; use recorded locality positives carefully and free help for genuine residual overlap. Do not turn an area inventory into an exclusive occurrence whitelist. - Pellegrinisaurus: Treat Anacleto as the preferred published interpretation of the exact type quarry, while retaining a qualified Allen alternative and avoiding an exclusive formation clue. - Avaceratops, Centrosaurus, Coronosaurus, Monoclonius, Spinops, Wendiceratops: Keep recent Avaceratops CMN 8804 referral, qualify lost-quarry Spinops alternatives, and use Wendiceratops lower Oldman type horizon positively without deleting historical or unknown comparative occurrences. - Daliansaurus, Jianianhualong, Liaoningvenator, Mei, Sinovenator, Sinusonasus: Retain the real five-genus Lujiatun assemblage; separate Baicai Gou positively without assigning Jianianhualong to Lujiatun or promising member clues always solve the crowding. ## Next admission gate PBDB determines included genus identities within the published scope and explicit holds. Review relationships and other facts against valid literature under the approved source policy. Validate candidate discovery/type anchors, all overlapping occurrences, material ambiguities and missing coverage; recompute every candidate after actual guesses and requested clues. Provide free distinguishing evidence when at least five unguessed answers remain indistinguishable after informative available tree probes and ordinary clues. Do not equate a potential source-screen split with an approved puzzle.
