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 Avaceratops was a relatively small ceratopsian dinosaur from the late Cretaceous of North America. What makes its classification difficult however is the fact that its neck frill is short and lacks any fenestrae (openings), and with the exception of others like Triceratops, ceratopsians can usually be divided into either centrosaurine or chasmosaurine groups, … 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
In Depth A very interesting discovery, Wendiceratops has been identified as one of the oldest centrosaurine ceratopsian dinosaurs so far discovered. At the time of writing only Xenoceratops and Diabloceratops are known to have been older. So far much of what we know about Wendiceratops has been pieced together by fragmentary and partial remains, but … Read more
In Depth Though only known from partial remains, Shixinggia seems to have been a fairly advanced oviraptorid. Asian oviraptosaurs seem to have been most common in Mongolia, but Shixinggia represents one of the few known to have been living within what are now the borders of China. The first oviraptosaur known to have lived within … Read more
In Depth Moros is a genus of primitive tyrannosauroid that lived in North America during the earlier stages of the Late cretaceous. The holotype fossils of Moros date from the Cenomanian of the Cretaceous, meaning that the discovery of these has turned back the clock on the first known appearance of a definitive tyrannosaur in … Read more
In Depth Jintasaurus is a genus of igaunodontid dinosaur that lived in China during the early Cretaceous. At the time of writing, Jintasaurus has only been described from partial skull fragments, though these seem to indicate that Jintasaurus was close to becoming a hadrosauroid, a member of the group of dinosaurs that would eventually give … Read more
In Depth A close relative of sauropod dinosaur genera such as Mendozasaurus and Futalognkosaurus, Quetecsaurus is at the time of its description one of the better known dinosaurs of its kind from the Cerro Lisandro Formation. Further Reading – A New Titanosaur (Dinosauria, Sauropoda) from the Upper Cretaceous (Cerro Lisandro Formation) of Mendoza Province, Argentina … Read more
