In Depth On a Chinese construction site in 1973 a dinosaur skeleton was accidentally processed by a mechanical composter. Unfortunately by the time the workers had realised what had happened much of the dinosaur had already been damaged and in some places completely destroyed by the machinery, but palaeontologists were still able to reconstruct and … Read more
In Depth Originally named as a species of Iguanodon by Richard Lydekker in 1888, the holotype fossils of this genus were actually named as a new genus twice in 2010, in two separate papers published that year. The holotype specimen was first named by David Norman as Barilium, and then by Kenneth Carpenter and Yusuke … Read more

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 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
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
