Adult Spinosaur Quadrate Skull Bone

3D ModelNoAI

A right quadrate bone of adult spinosaur. Most consistent with morphotype II. So I’ve tentatively assigned this to Sigilmassasaurus brevicollis. Part of the quadratojugal is also still attached in an articulated position. This specimen is slightly crushed laterally.

Location: Kem Kem Beds, Morocco

Age: Cenomanian, Late Cretaceous

Length: 20 cm
