Footprint type
Xiangxipus
Xiangxipus 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 100.5–66 million years old in China.
Confidence labels are switched off. Facts with low confidence, or where sources disagree, still carry a small dot: tap it for the reason.

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.
- Resting on one source: 4 facts come from a single source with nothing against them (rated medium): name (PBDB); authority (PBDB); 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…?
Same time, different places. Their fossils overlap in age, 83.6 to 66 million years ago, but no rock formation holds both.
Going by the ages and rock formations of their dated fossils, as on the map. Compare their fossil sites on the map.
