The big-headed Ocaron is named after an almost complete fossil found in Argentina in 1999. Its most unique feature is the non-horned mass on its head, which is a medium-sized theropod. The order Dinosaurs is a genus of Abelidosaurs, carnivorous subfamilies, more than 4 meters long, and hips about 1 meter high. It weighs about 700 kg.
Ocaron is not big, but looks very fit and compact. Its skull is almost the same height and length, and the eye sockets are slightly protruding, which makes it easy to observe the surroundings. Its neck is not long, and it is full of strong muscles, which is suitable for violent head movement when catching prey. Although its forelimbs have shown signs of degradation, the length is already relatively long in carnivorous dinosaurs. Due to the fusion of the talus and calcaneus into the tibia and sacrum, its hind limbs are very strong, and its feet have three functional toes It is convenient for Okalong to grasp the ground. Such a structure can make it rush out like an arrow when it starts.
