What isn't known 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); type species (PBDB); parent group (PBDB); age (headline) (PBDB); named after (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. Chinshakiangosaurus 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.
