In Depth Bothriospondylus has had a long taxonomic history as a sauropod dinosaur yet today the genus is regarded as dubious. This is because the type material of Bothriospondylus, really just a few vertebrae, has been so badly eroded that it is impossible to identify any unique features for the genus. This makes it impossible … Read more
In Depth Ligabuesaurus is a genus of titanosaurid dinosaur that lived in Argentina towards the end of the early Cretaceous. Ligabuesaurus was named in honour of Dr Giancarlo Ligabue, while the type species L. leanzai was named in honour of Dr. Hector Leanza, the geologist who discovered the holotype specimen.

In Depth In a nutshell Kotasaurus is one of the most primitive sauropod dinosaurs discovered. So primitive is Kotasaurus that the genus still possesses features that are known in sauropodomorph dinosaurs. This led to a lot of initial confusion over whether Kotasaurus was an advanced sauropodomorph, or a primitive sauropod, though today the interpretation of … Read more

In Depth With an estimated length of about nine meters long for the holotype individual, Sonidosaurus was actually pretty small for a late Cretaceous titanosaur. Hailing from the Iren Dabasu Formation, Sonidosaurus may have been preyed upon by tyrannosaurs of the time such as Alectrosaurus.

In Depth Cetiosauriscus is often confused with the similarly named Cetiosaurus, and this is no accident. The name Cetiosauriscus means ‘whale-lizard-like’, a reference to Cetiosaurus which itself means ‘whale-lizard’, so when Friedrich von Huene named the genus in 1927, he was actually saying that Cetiosauriscus was similar to Cetiosaurus. When the genus was first named … Read more
In Depth Tangvayosaurus is a genus of titanosaurid dinosaur that lived in what is now Laos during the early Cretaceous. Named from partial remains, fossils from a species of the Titanosaurus genus, ‘Titanosaurus’ falloti that is known from the same fossil bearing Formation that the Tangvayosaurus holotype fossils are known from, however some paleontologsts have … Read more
In Depth Named after the Mapuche word for the Colorado River (Muyelen) Muyelensaurus was a genus of titanosaur that lived in Argentina during the Coniacian of the Cretaceous. Muyelensaurus is notable by being a particularly gracile genus of titanosaur.

In Depth The description of Loricosaurus was first based upon the discovery of osteoderm armour that was initially perceived to have come from an ankylosaur. Later it was realised that these osteoderms actually came from a titanosaur, however, by themselves they are not very diagnostic of a distinct genus, which is why Loricosaurus is widely … Read more
In Depth The history of Galeamopus goes all the way back to 1902 when the first fossils were discovered in the US state of Wyoming. In 1906 the fossils were assigned to the Diplodocus genus, but in 1924 they were given their own species D. hayi, upon the basis that they were clearly different to … Read more
