Indosinosuchus

In Depth        Indosinosuchus is a genus of thalattosuchian‭ (‬sea crocodile‭) ‬that lived in waters around Asia,‭ ‬possibly around the late Jurassic or Early Cretaceous. Further reading -‭ ‬A new freshwater teleosaurid from the Jurassic of northeastern Thailand.‭ ‬Journal of Vertebrate Paleontology‭ ‬38‭(‬6‭)‬:e1549059.‭ ‬-‭ ‬J.‭ ‬E.‭ ‬Martin,‭ ‬S.‭ ‬Suteethorn,‭ ‬K.‭ ‬Lauprasert,‭ ‬H.-Y.‭ ‬Tong,‭ ‬E.‭ ‬Buffetaut,‭ ‬R.‭ … Read more

Xenotarsosaurus

In Depth        Based upon fossil remains first discovered in‭ ‬1980,‭ ‬Xenotarsosaurus was named because‭ ‬of‭ ‬the complete fusion between the astragalus and calcaneum bones of the ankle,‭ ‬something that is quite unusual for a theropod dinosaur.‭ ‬At the time of the original description,‭ ‬the rear leg of Xenotarsosaurus was shown to share some similarities with … Read more

Kuru

In Depth        Kuru is a genus of velociraptorine dromaeosaurid dinosaur that lived in Asia during the late Cretaceous. Further reading -‭ ‬A New Dromaeosaurid‭ (‬Dinosauria:‭ ‬Coelurosauria‭) ‬from Khulsan,‭ ‬Central Mongolia.‭ ‬American Museum Novitates.‭ ‬2021‭ (‬3982‭)‬:‭ ‬1‭–‬47.‭ ‬-‭ ‬James G.‭ ‬Napoli,‭ ‬Alexander A.‭ ‬Ruebenstahl,‭ ‬Bhart-anjan S.

Borogovia

In Depth        Borogovia is a genus of troodontid dinosaur that lived in Mongolia during the late Cretaceous.‭ ‬As a troodont,‭ ‬Borogovia would have been a predator,‭ ‬certainly capable of taking down smaller prey animals‭ ‬by itself.‭ ‬Also like other troodonts,‭ ‬Borogovia had a specialised second toe,‭ ‬but unlike them,‭ ‬the claw was not sickle shaped … Read more

Borealonectes

In Depth        Borealonectes is a genus of rhomaleosaurid pliosaur‭ ‬,‭ ‬a type of pliosaur that had a smaller head and longer neck than other larger pliosaurs such as Kronosaurus and Simolestes.‭ ‬The holotype fossils of‭ ‬Borealonectes were actually found within the Canadian Arctic,‭ ‬hence the name of the genus.‭ ‬Rhomaelosaurid pliosaurs like Borealonectes could be … Read more

Cetiosaurus

In Depth        One of the most common European sauropods of the Jurassic,‭ ‬Cetiosaurus is actually one of the most primitive.‭ ‬In more advanced sauropods the vertebrae are hollow as a weight saving feature,‭ ‬however Cetiosaurus has solid vertebrae which hint at its basal position in the evolution of sauropods.‭ ‬These solid vertebrae are similar to … Read more

Regaliceratops

In Depth        Officially named and described in‭ ‬2015‭ ‬from a single skull,‭ ‬Regaliceratops has already gone down as a particularly interesting ceratopsian dinosaur.‭ ‬The larger ceratopsians of the late cretaceous are usually divided into centrosaurines and chasmosauines,‭ ‬the former having large nasal horns and reduced frills,‭ ‬while the latter usually have reduced nasal horns and … Read more

Barbatodon

In Depth        Barbatodon is a genus of mammal that lived in Europe during the late Cretaceous. Further Reading -‭ ‬Prďż˝cisions sur les affinitďż˝s des Multituberculďż˝s‭ (‬Mammalia‭) ‬du Crďż˝tacďż˝ Supďż˝rieur de Roumanie‭ [‬Precise details on the affinities of the multituberculates‭ (‬Mammalia‭) ‬from the Upper Cretaceous of Romania‭]‬.‭ ‬-‭ ‬Comptes Rendus de l’Acadďż˝mie des Sciences ďż˝ Paris,‭ … Read more

Toyotamaphimeia

In Depth        Toyotamaphimeia was originally described as a prehistoric species of the Tomistoma genus,‭ ‬better known as the false gharial.‭ ‬Today the false gharial is known to attain lengths of up to five meters in the wild,‭ ‬with isolated skulls suggesting a theoretical limit of somewhere between five and a half and six meters long.‭ … Read more

Dryosaurus

dryosaurus

In Depth        The maximum adult size of Dryosaurus is difficult to estimate as all of the known specimens seem to represent animals that were still growing. What is known is that Dryosaurus was a bipedal dinosaur of the bird hipped group. It had a light build with long legs, long neck and a stiff tail, … Read more
