"Eobasileus cornutus" ("Crowned Dawn-King") is an extinct species of dinocerate mammal.

"Eobasileus" was 3 m (10 ft) long and stood 1.50 m (5 ft) tall at the shoulder. It looked very similar to the related "Uintatherium". Like "Uintatherium", it had three pairs of blunt horns on its skull, possibly covered with skin (like the ossicones of a giraffe). The frontal pair may have been composed of keratin, like the horn(s) of a rhinoceros. "Eobasileus" also had a pair of tusks which were shielded by bony protrusions of the lower jaw.
