Solid: the ages of its dated fossils, 161.5–143.1 million years ago (Omnisaura's calculation). Pale: the published range, 165.3–143.1 million years ago, which also counts records Omnisaura leaves out.

The last non-bird dinosaurs died out 66 million years ago. That's as far from us as the end of this bar.

Gaps are answers

What isn't known yet

  • Common names: no source we use gives it yet.
  • What it was named after: no source we use gives it yet.
  • Held back: 9 fossil records left out: identified only tentatively (for example "cf." or "?").
  • Resting on one source: 3 facts come from a single source with nothing against them (rated medium): type species (PBDB); parent group (PBDB); order (NHM).

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. Torvosaurus had gone at least 59.5 million years before Tyrannosaurus appears in the fossil record.
