Discovery
Abydosaurus is one of the few sauropods known from skull material, with the first described complete skull for a Cretaceous sauropod from the Americas.[1] It is also notable for its narrow teeth, as earlier brachiosaurids had broader teeth.[1]
Abydosaurus is based on the

Description
Although Abydosaurus lived some 50 million years after Giraffatitan, the skulls of these two genera are similar except for the narrower, sharper teeth and smaller nose of Abydosaurus. Abydosaurus can be differentiated from all other sauropods, including Giraffatitan, by subtle features of the nasal and maxillary bones, its relatively small external nares (nostrils), and some features of the teeth.[1] In 2012 Thomas Holtz gave a length of 18.3 metres (60 ft).[4]
