In Depth With a morphology like we see in lizards today, Thadeosaurus had a very long tail making up over half of its total body length. The legs were long and had long toes terminating in claws. It is likely that as Thadeosaurus walked, the toes would always be in contact with the ground. Thadeosaurus … Read more
In Depth At one time described as a species of Miacis, Dormaalocyon is a genus of carnivoramorph mammal that lived in Europe during the Eocene.

In Depth Simurghia is a genus of pterosaur that lived in Africa during the late Cretaceous. The holotype fossils of Simurghia were found in what was a marine environment, strongly showing that Simurghia lived in coastal ecosystems. Further Reading - Late Maastrichtian pterosaurs from North Africa and mass extinction of Pterosauria at the Cretaceous-Paleogene boundary. … Read more
In Depth Babibasiliscus is a relative of modern day basilisk lizards, some of which are also dubbed ‘Jesus Christ lizards’ for their ability to run across water for short distances. Babibasiliscus is best known from a skull, which when compared to average modern basilisk proportions yields an estimate of about sixty centimetres long for the … Read more
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 Mexichelys was originally described as a species of Euclastes, but was re-described to its own genus in 2010. Like relative genera, Mexichelys is thought to have been a durophagous carnivore of shelled organisms such as molluscs and crustaceans.

In Depth Before the description of Teinolophos in 1999, Steropodon was considered to be the earliest ancestor of the platypus. Comparison to mammals like the platypus has yielded body estimates of around forty to fifty centimetres long, something that would make Steropodon one of the larger known mammals of the early Cretaceous period. If Steropodon … 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. Further Reading – A redescription of “Megalosaurus” hesperis (Dinosauria, Theropoda) from the Inferior Oolite (Bajocian, Middle Jurassic) of Dorset, United Kingdom. – … Read more
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. Further Reading – Brachygnathosuchus braziliensis, a new fossil crocodilian from Brazil. - … Read more
