In Depth Mandschurosaurus is registered as a genus of hadrosaur that lived in what is now China during the late Cretaceous. Unfortunately the first individual ever found for this genus is so poorly preserved that most palaeontologists today regard the genus as a nomen dubium due to the difficulty of assigning further remains to the … Read more
In Depth Kritosaurus was first described in 1910 upon a description of a partial skull that was not only incomplete but partially eroded. To fill in the gaps, Brown used a second skull that would later be referred to Anatotitan to complete the reconstruction. Not all the fragments were used, and the final reconstruction was … Read more
In Depth The discovery of Suchomimus helped towards the more accurate reconstruction of its potentially much larger relative Spinosaurus. Combined with knowledge from the discovery of Baryonyx and new partial skull material attributed to Spinosaurus remains resulted in Spinosaurus finally being given a crocodile-like skull instead that of the more typical theropod skull style. These … Read more
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
