Footprint type
Eubrontes
Eubrontes 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 237–100.5 million years old in 10 countries, most often the United States and China.
Confidence labels are switched off. Facts with low confidence, or where sources disagree, still carry a small dot: tap it for the reason.

- Not known for certain. Footprints rarely show which animal made them.
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.
- Common names: no source we use gives it yet.
- What it was named after: no source we use gives it yet.
- Held back: 40 fossil records left out: identified only tentatively (for example "cf." or "?").
- Held back: 7 fossil records left out: identified as a related genus rather than this one.
- Resting on one source: 5 facts come from a single source with nothing against them (rated medium): name (PBDB); authority (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. Eubrontes had gone at least 16.9 million years before Tyrannosaurus appears in the fossil record.
