Tyrannomimus fukuiensis
(Fukui Tyrannosauroid Mimic)Etymology
Tyrannomimus is derived from the Greek "tyrannos" (tyrant) and "mimos" (mimic), referring to tyrannosauroids: a family of carnivorous "tyrant lizards", who have a similar vertical ridge on the ilium bone of their hips.
The species epithet, fukuiensis, means "from Fukui" in Latin.
