In Depth Arackar is a genus of titanosaur that lived in South America during the late Cretaceous. Though only known from partial remains, Arackar was at the time of its description one of the most complete individual dinosaurs discovered in Chile.

In Depth Like in other ornithocherid pterosaurs the sharp teeth of Boreopterus project out to the sides with the largest near the tip of the snout, most notably the third and fourth pairs from the tip of the snout. When the teeth near the tips of the jaws meshed together they made for an effective … Read more
In Depth Potentially, Aetosauroides is one of the oldest aetosaurs currently known, and is comparable in age to other genera such as Stagonolepis and Aetobarbakinoides. In fact Aetosauroides has been suggested to be a synonym to Stagonolepis on more than one occasion, though the wider consensus is that it is actually a separate genus. As … Read more
In Depth Fossils of Citipes were first described in 1933, but as a species of Ornithomimus. After this they subsequently moved into the Elmisaurus and Leptorhynchos genera respectively, before finally being described as a distinct genus in 2020. Citipes is a genus of oviraptosaur dinosaur that lived in North America during the late Cretaceous. Further … Read more
In Depth With a name that translates to English as ‘Monstrous murderer’, Teratophoneus has arguably one of the most apt names of any dinosaur, although the remains suggest that it was smaller than many of the other tyrannosaurids. The species name, T.curriei, is in honour of palaeontologist Philip J. Currie. Teratophoneus was a very interesting … Read more
In Depth At first glance the holotype specimen of Bellubrunnus was considered to have been an example of the famous pterosaur genus Rhamphorhynchus, though a closer study of the specimen soon came to the conclusion that it actually represented a unique genus. The skull of Bellubrunnus has been noted for being proportionately short with large … Read more
In Depth The holotype fossils of Antetonitrus were originally found in 1981, but were thought to be further fossils of the genus Euskelosaurus. It was not until over two decades later that they would be correctly described as a distinct genus. Antetonitrus is a very interesting sauropod dinosaur, as while it was quadrupedal (walked on … Read more
In Depth Tadzhikosuchus was a late Cretaceous era crocodile that lived in what would become Uzbekistan and Tajikistan. Three species were once named for the genus but a 2000 review resulted in the observation that no differences between the available fossils could differentiate three separate species. Therefore the species T. neutralis and T. kizylkumensis are … Read more
In Depth When first named in 2014, Atopodentatus made headlines around the world for the bizarre and hitherto unseen jaw arrangement. At the time of this reconstruction the jaws seemed to project forwards and then hook down and have numerous small teeth. These small teeth were postulated to have allowed Atopodentatus to filter out small … Read more
In Depth In 1876 Richard Owen named a new species of Poekilopleuron called P. pusillus. In 1879 this species was adjusted to P. minor by Edward Drinker Cope. Then in 1887 Harry Govier Seeley renamed this species as a new distinct genus, Aristosuchus. However, despite the name ‘suchus’ which is Ancient Greek for crocodile, this … Read more
