What isn't known yet

  • 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.
  • Resting on one source: 2 facts come from a single source with nothing against them (rated medium): parent group (PBDB); order (NHM).

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

The sources give different values. An editor hasn't ruled yet, so this is rated low until they do.

Did it meet…?

?

No. Loricatosaurus had gone at least 77.9 million years before Tyrannosaurus appears in the fossil record, a longer gap than the 66 million years between Tyrannosaurus and today.
