In Depth Since it was named in 1989, the dinosaur genus Bruhathkayosaurus has attained almost mythical status. The original description of the bones of this dinosaur were originally interpreted as belonging to a theropod dinosaur, though later study of the description has led readers to conclude that the remains were actually of a titanosaurid … Read more

In Depth Since the naming of the genus in 1893, Microcoelus has become something of a dubious genus of titanosaur. This is because at the time if writing only a single dorsal (back) vertebra is known. A humerus (upper arm bone) that was once assigned to the genus has now been moved to the genus … Read more

In Depth With an estimated length of about nine meters long for the holotype individual, Sonidosaurus was actually pretty small for a late Cretaceous titanosaur. Hailing from the Iren Dabasu Formation, Sonidosaurus may have been preyed upon by tyrannosaurs of the time such as Alectrosaurus.
