In Depth Way back during the 1890s, a fossil collector named Phillip James Rufford discovered a partial dorsal vertebrae near Hastings in East Sussex, England. Eventually catalogued as BMNH R2095, the vertebrae was first thought to belong the genus Cetiosaurus by Richard Lydekker, before eventually becoming Pelorosaurus conybeari. That was about it for well over … Read more
In Depth When fossils of Horshamosaurus were first discovered they were originally interpreted as coming from Iguanodon, but in 1996 they were re-described as a species of Polacanthus by William Blows. However in 2015 Blows re-described this species as a whole new genus named Horshamosaurus, citing clear differences in the vertebrae and armour. At the … Read more
In Depth It took a long time for the fossils of Neovenator to be studied and named, although such an occurrence is not unknown in the fields of Palaeontology. First discovered in 1978 from the chalk cliffs of the south-western Isle of Wight, a subsequent later visit led to the other remains of Neovenator being … Read more

In Depth As a creature that displays both dinosaurian and avian features, it is not known for certain how Rahonavis fits in with the evolution of birds from dinosaurs. This is problem shared with other discoveries such as Xiaotingia and even Archaeopteryx as the difining line of when a bird becomes a bird and not … Read more
In Depth First discovered in 2013, and named in 2015, Morelladon made headlines towards the end of 2015 as a rare example of a sailbacked dinosaur. Though dubbed a sailback, this sail was likely more like a hump as the neural spines of the vertebrae that supported it were very robust. These are way beyond … Read more
In Depth Tuojiangosaurus was the first stegosaurid to be discovered in China, and today remains the best known from Asia. Tuojiangosaurus itself is seen as a basal (primitive) form that displays a standard stegosaurid shape and posture while retaining features that would be lost in later genera. Tuojiangosaurus seems to have been limited to a … Read more
In Depth Moabosaurus is a genus of sauropod dinosaur that lived in North America during the early Cretaceous. Moabosaurus is thought to be a member Turiasauria group of sauropods.

In Depth Although based upon the description of fragmentary fossil remains, the actual discovery of Camarillasaurus is a significant revelation in itself since it is one of the few ceratosaurs known from the early Cretaceous period. This is directly in between the heyday of the ceratosaurs in the late Jurassic, and their second revival in … Read more
