In Depth Magnamanus is a genus of iguanodont dinosaur that lived in Spain during the early Cretaceous. The name Magnamanus means ‘large hand’, a reference to the enlarged well developed hands that this dinosaur genus adapted, notably more so than other known iguanodonts. The first individual of Magnamanus was at the time of its naming … Read more

In Depth Duriavenator was for a long time attributed to Megalosaurus, part of the ‘wastebasket taxon’ effect which saw Megalosaurus becoming a home for many fossils that actually represented similar yet different dinosaurs.

In Depth Brachygnathosuchus is a problematic genus of crocodile because so far it is only known from a small portion of a lower jaw and possible osteoderm. A partial mandible that was moved from Dinoschus into Brachygnathosuchus was later moved again into Purussaurus.

In Depth A kind of mosasaur known from North Africa, the species name of E. heterodontus means different-toothed and is in reference to the different kinds of teeth that are present in the jaws of known Eremiasaurus specimens. This is taken to indicate that Eremiasaurus may have been a generalist carnivore that was not especially … Read more
In Depth Saltoposuchus was not like todays crocodiles, in fact it was more like a small theropod dinosaur. The hind legs were long which meant that fast running speeds were theoretically possible, though the fore limbs may have still served a weight bearing function, perhaps when at rest. The teeth in the mouth were small … Read more
In Depth Lophostropheus was initially assigned as a specimen of Halticosaurus until 1993 it was re-classified as a second species of Liliensternus, a genus that was also previously established as a species of Halticosaurus. A new study in 2007 however concluded that while the fossils were similar, they were different enough to be established as … Read more

In Depth Qijianglong is a genus of sauropod dinosaur that lived in China during the late Jurassic. At the time of writing the genus is only known from a single juvenile, yet this juvenile is already fifteen meters long. It is uncertain how big Qijianglong could grow, but at fifteen meters just for a juvenile, … Read more
In Depth Unlike other pareiasaurs, Scutosaurus’s orientation of the legs was more under the body as opposed to out to the side. This gave Scutosaurus a much taller stance and would be more suitable for a creature that may have spent its time searching for suitable vegetation to eat in the arid environment of the … Read more
