Dilophosaurus Sinensis (Sinosaurus). Unlike dilophosaurus Wetherilli, this species is primarily nocturnal. Mainly inhabiting the island's forests. Like the cryolophosaurus, they are very agile and active. Their jaws are also more robust. And with larger eyes for seeing in low light, they are efficient killers. Unlike another nocturnal predator dilong, these animals are rarer to spot within the forests. The common prey item of this species is the avaceratops which too are nocturnal. Like their related species dilophosaurus, sinosaurus also possesses a pair of crests running along the top of its head which are used for display. With all this, sinosaurus is an interesting dinosaur indeed.
