Footprint type

Iguanodontipus

Sarjeant et al. 1998

Iguanodontipus 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 143.1–125.8 million years old in 6 countries, most often Germany and Spain.

Solid: the ages of its dated fossils, 143.1–125.8 million years ago (Omnisaura's calculation). Pale: the published range, 143.1–113.2 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.
  • Type species: 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: 3 facts come from a single source with nothing against them (rated medium): authority (PBDB); parent group (PBDB); order (NHM).

Size, diet and behaviour aren't covered yet. Omnisaura leaves them out rather than guess.

Did it meet…?

?

No. Iguanodontipus had gone at least 42.2 million years before Tyrannosaurus appears in the fossil record.
