In Depth Hypselospinus was a genus of ornithopod that was similar to Iguanodon, so similar in fact that the holotype remains of the genus were originally named as a species of Iguanodon, I. fittoni. These remains were re-described as a new genus by Norman in 2010, but not long after another name for the remains … Read more
In Depth Not a lot of information is currently available about Delapparentia, though as a relative to herbivorous dinosaurs like Iguanodon, a few things can be inferred. Delapparentia would have been a fairly large ornithopod dinosaur that would have balanced most of its body weight upon its rear legs, while the fore legs were reduced … Read more
In Depth The original bones of Mochlodon were first discovered in 1859, but were not formerly identified until 1870. When named by Emanuel Bunzel, the remains were identified as those of a new species of Iguanodon. However, by this time Iguanodon was being treated as a ‘wastebasket taxon’ for any remains that had a superficial … Read more
In Depth One of many small ornithopod dinosaurs from the Jurassic of China, there has been some speculation that Hexinlusaurus may actually represent a juvenile form of another ornithopod. Similar small ornithopods from the same formation as Hexinlusaurus include Agilisaurus, Yandusaurus and Xiaosaurus. Other herbivorous dinosaurs may have come across include stegosaurs Tuojiangosaurus and Huayangosaurus … Read more
In Depth A medium sized iguanodontid, dinosaur from the early Cretaceous of the USA, Planicoxa is established upon the partial remains of several individuals. As an iguanodontid, Planicoxa would have been a primarily quadrupedal dinosaur, though one with the capability to rear up and walk on just its hind legs when it needed to. Planicoxa … Read more
In Depth Although named from only a maxilla and tooth, the remains of this dinosaur are still complete enough to confidently identify it as an iguanodont. In life Siamodon would have been a medium to large sized ornithopod dinosaur that would have been primarily quadrupedal, but also occasionally bipedal. Although identified as being separate, Siamodon … Read more
In Depth A possible close relative of Gasparinisaura, Anabisetia was a fairly small ornithopod dinosaur that roamed around what would become South America during the early stages of the late Cretaceous. Anabisetia is known mostly from the partial post cranial remains of four specimens and a single partial brain case and lower jaw. The lack … Read more
In Depth Ajnabia is a genus of hadrosaurid dinosaur that lived during the late Maastrichtian period towards the end of the Cretaceous period. Ajnabia made headlines in the paleontological world when it was described as this represented the first time that hadrosaurid dinosaur fossils had been found in Africa. Hadrosaurid dinosaurs were for a long … Read more
In Depth Lurdusaurus is a genus of ornithopod dinosaur that lived in North Africa during the Early Cretaceous, and one that helped reveal that some ornithopods at least were growing to large sizes. Lurdusaurus is noted for being approximately nine meters long featuring a neck that is longer than most other ornithopods of its kind … Read more
In Depth Latirhinus should not be confused with Altirhinus, as not only do they have similar sounding names (only difference being the position of the ’l’ and ’a’ at the start), both were hadrosaurs and both were named after the enlarged bony protuberances on their snouts. Latirhinus was a form of saurolophine hadrosaur, a type … Read more
