In fact the shape of the skull of Nodocephalosaurus is actually more like the skulls of the ankylosaurs Saichania and Tarchia, both currently only known from central Asia. … Read more
In Depth Halisaurus was first named all the way back in 1869 during a period in American paleontological history today known as the ‘bone wars’.

In Depth Bissektipelta was first named as a species of Amtosaurus in 2002, however a subsequent evaluation of that genus found the type species, A. magnus to be indeterminate and possibly be those of a hadrosaur and not an ankylosaur. As such, the braincase that represented the second species, A. archibaldi was moved to its … Read more
