Solid: the ages of its dated fossils, 201.4–174.7 million years ago (Omnisaura's calculation). Pale: the published range, 201.4–168.2 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

  • Type species: no source we use gives it yet.
  • Order: no source we use gives it yet.
  • Diet: no source we use gives it yet.
  • Way of life: no source we use gives it yet.
  • Held back: 2 fossil records left out: identified only tentatively (for example "cf.", "?" or the name in quotation marks).
  • Resting on one source: 6 facts come from a single source with nothing against them (rated medium): authority (PBDB); parent group (PBDB); family (PBDB); age (headline) (PBDB); common names (Wikidata); named after (Wikidata).

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. Lufengosaurus had gone at least 91.1 million years before Tyrannosaurus appears in the fossil record, a longer gap than the 66 million years between Tyrannosaurus and today.
