In Depth Nanshiungosaurus was first described from partial remains mostly consisting of vertebrae in 1979. To begin with Nanshiungosaurus was thought to be a titanosaurian sauropod dinosaur, a bit later it was realised to be a therizinosaur. As a therizinosaur, Nanshiungosaurus was a theropod dinosaur that had adapted to a herbivorous diet instead of a … Read more
In Depth Ornithostoma was once considered to identical to Pteranodon, although modern thinking has it recognised as its own genus. Unfortunately Ornithostoma has suffered from the wastebasket effect with numerous poorly preserved remains being attributed to it. Although not much is known for certain, the toothless beak of Ornithostoma likely indicates a fish eating piscivorous … Read more
In Depth Barrosasaurus is a genus of sauropod dinosaur that lived in South America during the late Cretaceous. At the time of its description, the genus is only represented by three dorsal vertebrae. Further Reading - Barrosasaurus casamiquelai gen. et sp. nov., a new titanosaur (Dinosauria, Sauropoda) from the Anacleto Formation (Late Cretaceous: early Campanian) … Read more
In Depth Named in 2010, Kosmoceratops has quickly become a dinosaur fan favourite, thanks largely to the highly ornate form of the skull, which was also the inspiration for the genus name. To start, the frill section of the skull is twice as wide as it is long, which by physical proportions, means that it … Read more
In Depth The few scant fragmentary remains of Labocania make it very difficult to classify, but analysis of the post cranial elements suggest that it was a tyrannosaurid. What parts of the skull which are known are more robust however suggesting that Labocania had a differently shaped skull. It is easy to see why Labocania … Read more
In Depth Rhabdodon is for lack of a better term a puzzle. Although usually described as an iguanodont, Rhabdodon has also been considered as a hypsilophodont, and on top of this it has also been described as a ‘missing link’ between these two groups of dinosaurs. To further the confusion however, Rhabdodon lived in the … Read more
In Depth Protostega is one of the largest turtles to ever swim in the ocean and so far is only eclipsed by Archelon in terms of overall size. Like with Archelon, Protostega is thought to have had a ‘soft’ shell similar to the modern leatherback turtle (Dermochelys coriacea). Also like with Archelon, Protostega is thought … Read more
In Depth Manidens is a genus of heterodontosaurid dinosaur that lived in Argentina during the Late Cretaceous. As a heterodontosaurid dinosaur, Manidens had a combination of differently formed teeth within the mouth, and for this reason Manidens is often considered to have been omnivorous, however, so far no stomach contents have been identified to confirm … Read more
In Depth Dating from the Bathonian period, Kileskus is even older than Guanlong making it a contender for one of the earliest tyrannosaurs. The partial skull remains have revealed the presence of a crest that rose up from the snout. Beyond this the only thing that can be said about Kileskus is that it appears … Read more
In Depth Galleonosaurus is a genus of ornithopod dinosaur that lived in Australia during the early Cretaceous. The holotype for the genus is a hollow jaw bone, and at the time of writing no other fossil remains are known for this dinosaur. The name Galleoosaurus was chosen because when the fossil bone was held upside … Read more
