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.
- Held back: 1 fossil record left out: identified only tentatively (for example "cf.", "?" or the name in quotation marks).
- Resting on one source: 5 facts come from a single source with nothing against them (rated medium): parent group (PBDB); age (headline) (PBDB); common names (Wikidata); 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…?
No. Aegyptosaurus had gone at least 10.3 million years before Tyrannosaurus appears in the fossil record.
