In Depth The nasal horn of Einiosaurus is quite unusual in that it curves forward to point towards the ground, something which is reflected in the species name E. procurvicornis which translates to English as ‘forward curving horn’. In young Einiosaurus this horn is thought to have started out small, but as the individual grew … Read more
In Depth Scolosaurus was quick to become one of the better known ankylosaurid dinosaurs of the second half of the early twentieth century, at times rivalling even Ankylosaurus in popular media about dinosaurs. This was thanks largely to the relatively complete preservation of the holotype individual was considerably higher than most other ankylosaurids known at … Read more
In Depth The name Prosaurolophus was decided for this genus of hadrosaurid dinosaur on the basis that it was believed to have been similar to but lived before another genus called Saurolophus. However, this interpretation is now somewhat more controversial with different palaeontologists citing Prosaurolophus as being more closely related to other varying genera other … Read more
In Depth The material that would be named as Montanoceratops was originally assigned to Leptoceratops as a second species in 1935 as Leptoceratops cerorhynchos. However the original remains were incomplete and when further and more complete material was discovered by C. M. Sternbergi this second species of Leptoceratops was realised to be a different albeit … Read more
In Depth Machairoceratops is a genus of centrosaurine ceratopsian dinosaur that lived in North America during the late Cretaceous. At the time of the genus description in 2016, Machairoceratops is only known from partial skull and horn remains. We can however ascertain a few facts about this dinosaur. One is that Machairoceratops was a centrosaurine … Read more
In Depth Nipponosaurus is classed as a lambeosaurine hadrosaurid because of the hollow head crest that rises up from the top of the snout, though the incomplete nature of the known remains makes it hard to establish fine details, and reconstructions are usually completed with comparisons to other better preserved genera. Also, because the fossils … Read more
In Depth An often included genus in dinosaur books, Arrhinoceratops is another example of a popular dinosaur known by very little fossil material. In this case Arrhinoceratops has been based upon the description of only a single partially preserved skull. Arrhinoceratops was named because William Parks thought that it lacked a nasal horn, and too … Read more
In Depth With study of Scelidosaurus going all of the way back until the mid-nineteenth century, Scelidosaurus is one of the oldest genera of dinosaur known. In addition to that, out of all the dinosaurs that are known from the British Isles, Scelidosaurus is represented by some of the most complete fossil material. Scelidosaurus was … Read more
In Depth Glishades is a genus of hadrosauroid dinosaur that lived in North America during the late Cretaceous. Since a paper was published suggesting that Glishades is actually an indeterminate juvenile (Campione et al, 2012), the genus has become widely regarded as a nomen dubium.
