Branch Survey · PBDB classification captured 9 October 2026
Where the trail needs more evidence.
A review of the 1,308 genera remaining after our agreed name holds. We look for genera directly attached to the same parent whose source diet, broad period and discovery-region values match. Their hidden-answer eligibility is still pending.
Pool sizes are before guesses. Automatic help requires five remaining, unguessed possibilities. 60 pools could reach that threshold in the source-tree model. The three boundary cases—Centrosaurini, Nasutoceratopsini, Pachycephalosaurinae—start at five, but reaching their branch requires testing one of them and leaves four.

Counts assume the full PBDB hierarchy is retained. They include direct genus children, not every descendant of the named group. Other subgroups can still be distinguished through tree guesses.

What needs checking
These figures screen the database; they do not approve 484 hidden answers. Most diets are inherited from higher taxa. 3 matching pools preserve multiple source diet categories: Troodontidae and the two Ornithomimidae pools. A supported interpretation, with a reference and any uncertainty qualifier, is needed before assigning a fixed gameplay clue.
Another 131 genera have incomplete screening evidence: 76 lack diet data, 24 have no genus-linked occurrence, and 33 need locality-level mapping for Russia, Kazakhstan or offshore code O2. These counts overlap. Missing data is never treated as an identical clue, and these genera remain in the roster review queue.
Oceania and Antarctica are separate diagnostic regions here. The current four-region prototype cannot cover the expanded roster without reviewing its region scheme. Periods come from the union of individual occurrence intervals against the captured PBDB timescale; a span across a boundary can reflect dating uncertainty, rather than continuous genus survival.
For a sensitivity check, excluding explicitly qualified cf., aff. and ? records produces 65 pools covering 496 genera. Narrower source location lists can make some pools larger, so this is not simply a smaller roster. The five largest pool memberships stay the same in both screens. Both scenarios need occurrence review.

Preserve the useful branches
Reusing only the clade names present in the current 36-genus prototype would merge additional source groups: this diagnostic projection creates 71 pools covering 836 genera. Its largest crowd is 71 American Cretaceous herbivores under Macronaria. That is a consequence of omitted labels, not a proposed scientific classification.
The expansion should keep useful PBDB branches in the underlying dataset. Compact display can hide linear labels visually while retaining them for relationship feedback. No new ancestry amendment or roster expansion is applied by this survey.

Sources and next review
Classification and occurrences use the wire-hash-verified PBDB snapshot from 9 October 2026, filtered through our recorded roster policy. PBDB interval bounds were separately captured on 10 October: Triassic 251.902–201.4 Ma, Jurassic 201.4–143.1 Ma, Cretaceous 143.1–66 Ma. These are the database bounds used for this screen.
The Locality Survey now checks all 108 large parent groups and all 63 matching pools against every linked occurrence, preserving overlapping and uncertain footprints. Potential formation and locality splits remain evidence-review leads. Keep admission as a hidden answer pending until fair residual counts are validated. See the complete locality review →.
