Purussaurus

purussaurus

In Depth        At between eleven and thirteen meters long it goes without saying that Purussaurus was an apex predator capable of attacking large prey.‭ ‬As a caiman crocodile,‭ ‬Purussaurus had an extremely stout and robust skull that housed large conical teeth suited for gripping and holding onto powerful prey.        Purussaurus is one of the growing … Read more

Crichtonsaurus

In Depth        Crichtonsaurus seems to have been a fairly small genus of ankylosaur that lived in China during the earlier stages of the Late Cretaceous period.‭ ‬As an ankylosaur Crichtonsaurus would have been a squat quadrupedal dinosaur that browsed upon low growing plants.        At the time of writing two species of Crichtonsaurus have been identified … Read more

Ojoceratops

In Depth        Fossils sitting in a museum and sometimes thought to belong to one kind of ceratopsian dinosaur are sometimes found to actually represent another upon later examination.‭ ‬This is how others such as Mojoceratops and Spinops were discovered,‭ ‬and is also how Ojoceratops was discovered.‭ ‬Ojoceratops was classed as Torosaurus,‭ ‬but‭ ‬is thought to … Read more

Gavialimimus

In Depth        Gavialimimus is a genus of mosasaur that lived in waters around North Africa during the latest Cretaceous.‭ ‬Gavialimimus is noted for its jaws which are substantially longer and more slender than those of most other mosasaurs.‭ ‬This would clearly be an adaptation for specialised feeding,‭ ‬possibly for either fish or squid.‭ ‬This may … Read more

Makhaira

In Depth        Makhaira is a genus of pliosaur that lived in waters that once submerged parts of Russia during the early Cretaceous.‭ ‬Due to lack of fossil material,‭ ‬little is known about the overall details of Makhaira.‭ ‬But these remains seem to have come from a small to medium sized pliosaur.‭ ‬The known teeth of … Read more

Triopticus

In Depth        At the time of the genus description very little is known about Triopticus.‭ ‬Only known from a partially preserved braincase,‭ ‬we don‭’‬t know the size of Triopticus,‭ ‬what it ate,‭ ‬or even what kind of creature it was other than just giving it the‭ ‬tentatively cautious title of being an archosauriform.‭ ‬What we … Read more

Sarmientosaurus

In Depth        Named from a skull and seven neck vertebrae,‭ ‬Sarmientosaurus is a‭ ‬genus of titanosaur that lived in South America during the early stages of‭ ‬the Late Cretaceous.‭ ‬Sarmientosaurus is noted for having eyes sockets that were proportionately larger than in other titanosaurs.‭ ‬Studies of the inner ear area also show that held was … Read more

Walgettosuchus

In Depth        Although the genus name means crocodile,‭ ‬Walgettosuchus was actually a theropod dinosaur,‭ ‬although the single‭ ‬opalised‭ ‬vertebrae that it is known from has been criticised as not being diagnostic enough to establish a specific genus.‭ ‬As such Walgettosuchus is generally regarded as being what is called a nomen dubium,‭ ‬a genus that cannot … Read more

Uteodon

In Depth        Originally named as a species of Camptosaurus,‭ ‬Uteodon was a fairly primitive iguanodont dinosaur that lived in what is now Utah during the late Jurassic.‭ ‬As an iguanodont,‭ ‬Uteodon would have been a primarily quadrupedal plant eater,‭ ‬though it may have still reared up on its hind legs to reach higher vegetation.‭ ‬Possible … Read more

Kelumapusaura

In Depth        Kelumapusaura is a genus of hadrosaurid dinosaur that lived in South America during the late Cretaceous.‭ ‬The establishment of Kelumapusaura was born out of the discovery of a bone bed of at least several individuals. Further reading -‭ ‬A new hadrosaurid‭ (‬Dinosauria:‭ ‬Ornithischia‭) ‬from the Late Cretaceous of northern Patagonia and the radiation … Read more
