In Depth Chilesaurus is a very exciting find, and not just because it was the first Jurassic aged dinosaur to be discovered in Chile. Chilesaurus is a theropod dinosaur, yet there is no doubt that Chilesaurus was a plant eater, and not a carnivore like most other theropods were. Firstly the teeth of spatulate and … Read more
In Depth Remains of Suskityrannus were first announced back in 1998 when the description of the ceratopsian dinosaur Zuniceratops was first published. Back then the fossil remains were thought to have been those of a dromaeosaur, but in 2019, a more detailed analysis of these fossils were published. The name chosen for this dinosaur was … Read more
In Depth The name Carcharodontosaurus is derived from the Carcharodon genus of sharks, a group famous for including the great white shark (Carcharodon carcharias). This name was chosen because the teeth are sharp and serrated in a similar manner to the great white sharks, something that meant they could slice through the flesh of prey … Read more
In Depth Although only described from a single upper jaw bone, Matheronodon is noteworthy among ornithopod dinosaurs for having teeth that are larger, but fewer in number to most other known ornithopods. The describers speculated that Matheronodon used a scissoring action to eat plants. Further Reading - Extreme tooth enlargement in a new Late Cretaceous … Read more
In Depth Leonerasaurus is a genus of sauropodomorph dinosaur that is known to have lived in South America during the early Jurassic. Leonerasaurus is notable for having a mix of physical characteristics that are seen in both sauropodomorph dinosaurs as well as later sauropods, though current thinking is that Leonerasaurus was a sauropodomorph, but one … Read more
In Depth Like with many dinosaurs named from English fossils in the nineteenth century, Lexovisaurus has a complex taxonomic history, but it can be broken down like this. Current fossils of Lexovisaurus were originally described in 1887as Omosaurus a genus that had different species. However it was later realised that the name Omosaurus was preoccupied, … Read more
In Depth Euhelopus was originally named Helopus until it was discovered that the name had already been used for a bird. The name was altered to Euhelopus by Alfred Romer in 1956. Euhelopus was similar to the macronarian sauropods in that the fore legs were proportionately longer than the rear legs, something that would have … Read more
In Depth The holotype specimen of Spinops was first discovered in 1916 by Charles H. and Levi Sternberg. However when the material was sent to the London Natural History Museum (the institution that financed the dig) the keeper of Geology, one Arthur Smith Woodward (today best remembered for declaring the ‘Piltdown Man’ as a genuine … Read more
In Depth Dinosaurs and other extinct prehistoric animals often have complicated histories regarding classification and Chirostenotes is no exception to this. First only the hands were found by George Fryer Sternberg in 1914. First to study them were Lawrence Morris Lambe who unfortunately died before he had chance to finish the description of them. Charles … Read more
In Depth Initially thought to be a tiny abelisauroid at the time of discovery, the lack of fusing in the vertebrae is now seen as proof that the individual which makes up the holotype is actually a juvenile. Unfortunately, because the remains of Ligabueino are so incomplete, it is hard to ascertain exactly what kind … Read more
