Estemmenosuchus ("Crowned Crocodile") is a genus of large, early omnivorous therapsid that lived during the middle part of the Middle Permian period. It was among the largest animals of its day, and is characterised by distinctive horn-like structures, probably for intra-specific display. Two species of Estemmenosuchus are known, both from the Perm (or Cis-Urals) region of Russia.
Jurassic Park FranchiseEdit
Estemmenosuchus did not appear in the Jurassic Park novels or the movies. It only appeared in two Jurassic Park toy lines: Jurassic Park Series 2 as a prototype and The Lost World Series 1 in a set with Scutosaurus.
