In Depth Dahalokely is so far only known by very incomplete remains, but if it’s identification as an abelisauroid is correct, then it certainly was very small for its type. Alternatively, if Dahalokely turns out to be a noasaur, a group of theropods closely related to abelisaurs, then it would be expected to have a … Read more
In Depth Dyslocosaurus is a genus of diplodocid sauropod dinosaur that lived in North America during the late Jurassic. It is unknown exactly where the type fossils of Dyslocosaurus are known from as when they were first discovered they only had ‘Lance Creek’ written on them.

In Depth Chenanisaurus is a genus of abelisaurid dinosaur that lived in North Africa towards the end of the Cretaceous period. Chenanisaurus is named from the description of a partial lower jaw, and while this does not give us much to go on, it does reveal a few things. While the jaw is incomplete, it … Read more
In Depth The creation of the Bellusaurus was born out of the discovery of a bonebed of at least seventeen individuals. Features on some of these fossil such as the lack of fusion on some parts means that these individuals are probably juveniles and therefore not fully grown. It has also led to speculation that … Read more
In Depth Originally described as a species of Aeolosaurus, A. maximus was established as its own genus, Arrudatitan, in 2021. Arrudatitan was established from partial remains including limbs, shoulder, hip and various vertebrae. Aside from being distinct from Aeolosaurus, Arrudatitan is noted for being fairly lightly built when compared to other titanosaur genera as a … Read more
In Depth The partial skeletal remains that the Drusilasaura genus is known by have been seen to be indicative of a lognkosaurian titanosaur. If this analysis is correct then Drusilasaura would be the oldest known lognkosaurian titanosaur. Further Reading – Drusilasaura deseadensis gen. et sp. nov., a new titanosaur (Dinosauria-Sauropoda), of the Bajo Barreal Formation, … Read more
In Depth Named after the famous palaeontologist Jos� Fernando Bonaparte for his contributions to the advancement of palaeontology, Bonatitan seems to have actually been quite a small titanosaur. Hailing from the Allen Formation, Bonatitan likely shared its habitat with other dinosaurs such as other titanosaurs like Saltasaurus, Laplatasaurus, Aeolosaurus and Rocasaurus and the hadrosaurs Lapampasaurus … Read more
In Depth There has been some contention over exactly what kind of theropod dinosaur Austrocheirus was. When described, Austrocheirus was identified as an abelisauroid theropod via cladistic analysis. This was significant because this would have been the first example of an abelisauroid theropod which did not feature the forelimb reduction which is often used as … Read more
In Depth Garrigatitan is a genus of titanosaur that lived in Western Europe during the late Cretaceous. Known only from partial remains of an immature individual, Garrigatitan seems to have been a fairly small titanosaur, even when fully grown. Further Reading - A new titanosaur (Dinosauria: Sauropoda) from the Upper Cretaceous of Velaux-La-Bastide Neuve (southern … Read more
In Depth The naming of Angolatitan was a very important discovery for the country of Angola because it was the first genus of dinosaur known to have come from there. Angolatitan is so far known only from a partial right fore limb, so details like size or a specific dietary preference beyond just plants are … Read more
