In Depth Fossil teeth of Igdamanosaurus were originally described as a species of the mosasaur Globidens by Zdansky in 1935, a later study of a partial jaw from Niger by Lingham-Soliar in 1991 saw the remains raised to the status of a distinct genus. Additionally Igdamanosaurus is now classed within the Plioplatecarpinae due to the … Read more
In Depth Tornieria fossils were first found in 1907 and described the next year by the German palaeontologist Eberhard Fraas. However, at this time Fraas decided to call the new genus Gigantosaurus, but the problem with this is that the name Gigantosaurus had already been used by Harry Govier Seeley to name a genus of … Read more
In Depth Kataria was a macrostomatan snake that lived in Bolivia during the Danian stage of the Paleocene. At the time of its description, Kataria was the oldest macrostomatan snake known from South America. As a macrostomatan snake, Kataria would be expected to be able to disarticulate its jaw so that it could swallow larger … Read more

In Depth Although the body is still unknown, Thililua is considered to be a polycotylid plesiosaur. Named after the genus Polycotylus, polycotylids had plesiosaur shaped bodies, but proportionately shorter necks and longer jaws, with probably the most famous example of this group being Dolichorhynchops. Although most polycotylid fossils are known from North America, the presence … Read more
Intro of Struthiomimus Struthiomimus remains were actually known all the way back to 1901, but were interpreted by Lawrence Lambe to belong to Ornithomimus altus, the first ornithomimid to be named. In 1917 however, Henry Fairfield Osborn (the man who is perhaps best remembered for naming Tyrannosaurus) identified key differences in the bones, especially the … Read more
In Depth Sometimes dubbed the ‘Asian Iguanodon’, Probactrosaurus is no way near as well-known as its older and far more famous relative (which was actually the second dinosaur genus named, and the first one named that ate plants). At roughly five and a half meters in length Probactrosaurus was actually quite small when compared to … Read more
In Depth Chupacabrachelys is a genus of side-necked turtle known to have lived in what is now Texas during the late Cretaceous. As a side necked (pleurodiran) turtle, the head would not have retracted under the shell, but rather folded back under the side. Further to being a pleurodiran, Chupacabrachelys is also a bothremydid turtle, … Read more
In Depth Dollosaurus is a genus of mosasaur that swam and hunted in the seas of Europe during the Campanian stage of the Late Cretaceous. Dollosaurus was named after Louis Dollo, a Belgian palaeontologist who is remembered for his work studying mosasaurs.
