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
- Common names: no source we use gives it yet.
- What it was named after: no source we use gives it yet.
- Held back: 1 fossil record left out: identified only tentatively (for example "cf." or "?").
- 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); order (NHM).
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…?
No. Lycorhinus had gone at least 109.3 million years before Tyrannosaurus appears in the fossil record, a longer gap than the 66 million years between Tyrannosaurus and today.
