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.
- What it was named after: no source we use gives it yet.
- Held back: 3 fossil records left out: identified only tentatively (for example "cf." or "?").
- Resting on one source: 4 facts come from a single source with nothing against them (rated medium): parent group (PBDB); family (PBDB); age (headline) (PBDB); common names (Wikidata).
Size, diet and behaviour aren't covered yet. Omnisaura leaves them out rather than guess.
Where sources disagree
None open. Where our sources overlap, they agree on everything shown here.
Did it meet…?
No. Plateosaurus had gone at least 115.9 million years before Tyrannosaurus appears in the fossil record, a longer gap than the 66 million years between Tyrannosaurus and today.
Going by the ages and rock formations of their dated fossils, as on the map. Compare their fossil sites on the map.
Lived alongside
Genera found in the same rock formations, from rocks of the same age.
