Gaps are answers
What isn't known yet
- Type species: 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.
- Held back: 3 fossil records left out: identified as a related genus rather than this one.
- Resting on one source: 4 facts come from a single source with nothing against them (rated medium): authority (PBDB); parent group (PBDB); order (NHM); 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.

Did it meet…?
No. Mochlodon had gone at least 0 million years before Tyrannosaurus appears in the fossil record.
