Footprint type

Breviparopus

Dutuit and Ouazzou 1980

Breviparopus is a footprint type: the name is for the fossil footprints themselves. The animal that made them is not known for certain. Its footprints are found in rocks 161.5–149.2 million years old in Morocco and the United Kingdom.

Solid: the ages of its dated fossils, 161.5–149.2 million years ago (Omnisaura's calculation). Pale: the published range, 174.7–149.2 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

  • The animal that made them: not known for certain, as for most footprint types.
  • Order: 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: 5 fossil records left out: identified only tentatively (for example "cf." or "?").
  • 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); family (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. Breviparopus had gone at least 65.6 million years before Tyrannosaurus appears in the fossil record.
