"Estemmenosuchus" ("Crowned Crocodile") is a genus of large, early omnivorous therapsid that lived during the middle part of the Middle Permian period. It was the largest animal of its day, and is characterised by distinctive horns-like structures, probably for intra-specific display. Two species of "Estemmenosuchus" are known, both from the Perm (or Cis-Urals) region of Russia.

Description

, growing upwards and outwards from the sides and top of the head.

The skull superficially resembles that of "Styracocephalus", but the "horns" are formed from different bones; in "Estemmenosuchus" the horns are located on the frontals and directed upwards, whereas in Styracocephalus the horns are formed by the tabular and extend to the rear.

Two species of "Estemmenosuchus" are known; they differ in size, shape of the skull, and shape of the horns.
