In Depth Originally named as a species of Rhynchosaurus, R. brodiei was established as a distinct genus in 2016 and granted the name Langeronyx. As a rhynchosaur Langeronyx would have been a squat plant eating reptile that lived during the Triassic.

In Depth Not much is known about this dinosaur except that the forelimbs appear to be quite large for a large carnivorous theropod. The discoverer theorised that it may of actually been quadrupedal, but this has since been refuted by other palaeontologists. Further Reading – [A new theropod dinosaur from the Middle Jurassic of Sichuan … Read more
In Depth Qiupanykus is a genus of alvarezasurid dinosaur that lived in Asia towards the end of the Cretaceous. Eggs of oviraptorid dinosaurs found near the holotype skeleton of Qiupanykus have led the describers of the genus that maybe Qiupanykus, and perhaps other alvarezsaurs, used the stout claws on their forelimbs to punch holes in … Read more
In Depth A poorly known genus of hadrosaurid dinosaur, Pararhabdodon fossils were initially thought to be from a species of the genus Rhabdodon. New study resulted in the establishment of a new genus, Pararhabdodon, with the description being based upon the caudal (tail) vertebrae. Early fossil assignment for the genus was mostly vertebrae with a … Read more
In Depth Tangvayosaurus is a genus of titanosaurid dinosaur that lived in what is now Laos during the early Cretaceous. Named from partial remains, fossils from a species of the Titanosaurus genus, ‘Titanosaurus’ falloti that is known from the same fossil bearing Formation that the Tangvayosaurus holotype fossils are known from, however some paleontologsts have … Read more
In Depth Janusaurus is a genus of ophthalmosaurid ichthyosaur that lived in the waters around what is now Spitsbergen during the late Jurassic.

In Depth Like with most flat headed pachycephalosaurs, the genus Dracorex may well represent a juvenile of another genus. This is because there seems to be an emerging pattern where pachycephalosaurs had flat heads when they hatched out of the eggs, but growing into domes as the dinosaur grew to adulthood. In this respect Dracorex … Read more
In Depth Kaijiangosaurus is only known from very fragmentary remains, so it is difficult to establish exactly where it belongs in relation with other dinosaurs. Further remains have been attributed to the genus but are currently undescribed, but some palaeontologists have leaned towards a classification within the Megalosauridae (the theropod dinosaur group typified by Megalosaurus). … Read more
In Depth Koreaceratops made headlines in 2011 for two reasons, the first being that this was the first ceratopsian dinosaur to be discovered in South Korea. The second is the theory that Koreaceratops may have been semi aquatic. The latter is idea is based upon the observation of the tall neural spines of the recovered … Read more
In Depth In 1941 an alligator specimen from the Green River Formation was interpreted as being a new species of Hassiacosuchus by C. C. Mook. However a later 1967 study by Wassersug and Hecht found the remains of the second species actually belonged within the Procaimanoidea genus, and as such the second species of Hassiacosuchus … Read more
