Gaps are answers
What isn't known yet
- Type species: no source we use gives it yet.
- Order: no source we use gives it yet.
- Family: no source we use gives it yet.
- Common names: no source we use gives it yet.
- Resting on one source: 5 facts come from a single source with nothing against them (rated medium): authority (PBDB); parent group (PBDB); age (headline) (PBDB); named after (Wikidata); diet (PBDB).
Size and appearance aren't covered yet, and diet and way of life only as PBDB infers them for the wider group. Omnisaura leaves the rest out rather than guess.
Where sources disagree
None open. Where our sources overlap, they agree on everything shown here.
Did it meet…?
Same time, different places. Their fossils overlap in age, 83.6 to 72.2 million years ago, but no rock formation holds both.
