Gaps are answers

What isn't known yet

  • The animal that made them: not known for certain, as for most footprint types.
  • 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.
  • 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: 2 facts come from a single source with nothing against them (rated medium): parent group (PBDB); age (headline) (PBDB).

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