01 / DEFINITION & ECOLOGY
What was Eotitanops?
Eotitanops (Eotitanops borealis) was an extinct organism known from About 53–48 million years ago, with a range in Warm forest and river valley · North America.
Life and ecology
It browsed soft leaves in forests as an early relative of later giant horned brontotheres.
02 / DISAPPEARANCE
Why did Eotitanops disappear?
Brontotheres grew larger and turned over rapidly in the middle Eocene, but this does not prove that larger forms directly replaced this small one.
03 / EVIDENCE
How do scientists know about Eotitanops?
Skulls, teeth and limb bones document early brontothere evolution; relationships among primitive perissodactyls remain revised.

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.
