In Depth At fifteen meters long it could be said that Datousaurus was a lower average in terms of sauropod sizes of the Jurassic era. The skull of Datousaurus is noted as being deep with ‘spoon-shaped’ teeth for processing plants. Datousaurus is also noted for having a higher reach than some other sauropods that lived … Read more
In Depth Chromogisaurus is a genus of sauropodomorph dinosaur that lived in South America during the late Triassic. At only about two meters long, Chromogisaurus was small for its kind, though certainly not unique. The main predators of Chromogisaurus would have mainly been the emerging theropod dinosaurs, though late surviving rauisuchians would have been potential … Read more
In Depth Not many fossilised bones of this dinosaur are known, but those that are are simply huge. Comparing these bones to the more complete remains of other genera has resulted in very rough estimates of around thirty meters long, raising the probability that Ruyangosaurus was one of the largest animals to ever walk the … Read more
In Depth Janenschia is a genus of titanosaur that has a classification history closely tied to the African diplodocid sauropod Torneria and by extension the North American Barosaurus and the English Gigantosaurus. We start in England in 1869 when Harry Govier Seeley named Gigantosaurus based upon a few vertebrae, partial limb bones and an osteoderm. … Read more
In Depth An early Cretaceous sauropod from Spain, Aragosaurus is considered to have been similar to the North American Camarasaurus in form. This means that the head would have been carried up high to enable Aragosaurus to browse upon the upper branches of trees, which were simply beyond the reach of low browsing dinosaurs. This … Read more

In Depth Lessemsaurus is a genus of sauropod dinosaur named in honour of the Don Lessem, an author noted for his work writing popular science books. Although Lessemsaurus is so far only based upon the description of vertebrae. These vertebrae are noted for having tall neural spines, something which may hint at a fleshy or … Read more
In Depth Like with many sauropod dinosaurs, Agustinia is known from incomplete remains. Some of these remains however revealed a startling revelation in that this sauropod had what appeared to be armour along its back similar in appearance to the plates of Stegosaurus, a herbivorous but completely different kind of dinosaur. This is in particular … Read more
In Depth Sometimes when people hear the name Antarctosaurus they assume that this dinosaur lived in Antarctica where in actuality it lived in Argentina. Antarctosaurus means ‘southern lizard’ and here it is a reference to being found on a southern continent. However the real problem with Antarctosaurus is that it is known from very incomplete … Read more
In Depth One of the most notable details of Rebbachisaurus are the tall neural spines of the vertebrae, which either stood proud from the back, or supported a sail or hump that ran along the spine. Aside from this Rebbachisaurus was a fairly generic diplodocid sauropod with a large build, long neck and whip-like tail. … Read more
