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.
  • 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): authority (PBDB); type species (PBDB); parent group (PBDB); age (headline) (PBDB).

Size and appearance aren't covered yet, and diet and way of life only as PBDB infers them for the wider group. Omnisaura leaves the rest out rather than guess.

Where sources disagree

None open. Where our sources overlap, they agree on everything shown here.

Did it meet…?

?

No. Boutakioutichnium had gone at least 65.6 million years before Tyrannosaurus appears in the fossil record.
