Gaps are answers
What isn't known yet
- Type species: no source we use gives it yet.
- What it was named after: no source we use gives it yet.
- Resting on one source: 5 facts come from a single source with nothing against them (rated medium): authority (PBDB); parent group (PBDB); order (NHM); common names (Wikidata); diet (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
1 openAge
- 100.5–93.9 MaPBDB
- 113.2–100.5 MaNHM specimens
The ages of the records reach well beyond the published range. An editor hasn't ruled yet, so this is rated low until they do.
Did it meet…?
No. Anoplosaurus had gone at least 10.3 million years before Tyrannosaurus appears in the fossil record.
