os nasal

Le crâne de "Deinonychus" était toutefois différent de celui du "Velociraptor" car le sommet de son crâne était plus solide, comparable à celui de "Dromaeosaurus" et il n'avait pas les os nasaux déprimés de "Velociraptor".

The skull of "Deinonychus" was different from that of "Velociraptor", however, in that it had a more robust skull roof, like that of "Dromaeosaurus", and did not have the depressed nasals of "Velociraptor".
