01 / DEFINITION & ECOLOGY
What was Deltadromeus?
Deltadromeus (Deltadromeus agilis) was an extinct organism known from About 96 million years ago, with a range in River delta and open plain · Morocco.
Life and ecology
It pursued prey across North African waterways, though its placement among ceratosaurs or other theropods remains disputed.
02 / DISAPPEARANCE
Why did Deltadromeus disappear?
Late Cretaceous environmental and predator turnover provides context, but the fossil record does not establish why the genus disappeared.
03 / EVIDENCE
How do scientists know about Deltadromeus?
A partial skeleton preserves limbs, pelvis and vertebrae; the missing skull keeps appearance and affinity cautious.

05 / REVISION HISTORY
How has this record changed?
- Rewrote an extinction cause that presented environmental or faunal turnover as established; it is now given as context the record does not prove.
- Verified authoritative entity sources and added three responsive reconstruction sizes.
- Initial bilingual species record published.
