In Depth Mei was named because it was found in a sleeping pose, not unlike birds today. Study of the bones has revealed they were not totally fused, meaning that the animal was a juvenile. Analysis of the stone the fossil was discovered in shows it to have been buried by volcanic ash. A second … Read more
In Depth Lapampasaurus is a late Cretaceous era genus of hadrosaur. Although only named from partial remains, the discovery is of yet another hadrosaur from South America. The continent of South America has long been assumed to have been isolated from North America during the Cretaceous, but the presence of hadrosaur genera such as Lapampasaurus, … Read more
In Depth Cynthiacetus was very similar to the famous Basilosaurus, one of the largest and most famous of the primitive archaeocetid whales. In fact the skull of Cynthiacetus is very similar to the skull of Basilosaurus in both size and form, but Cynthiacetus is known to be different by the simple observation that the vertebrae … Read more

In Depth Mammacyon was a ‘bear dog’ that has been assigned to the Temnocyoninae, and not surprisingly is thought to have been considered to be similar to the group type genus Temnocyon. Mammacyon seems to have been active at the same time as Temnocyon as well as many of the same locations, although the current … Read more
In Depth Although only named from a partial upper jaw, this is still enough to identify Angulomastacator as a distinct genus of hadrosaurid dinosaur because the front portion of the jaw bends down at an angle of forty-five degrees. If you are unfamiliar with how much this each, look at or imagine a clock face … Read more
In Depth Almost nothing is known about this pterosaur, not even its position and relationship amongst other pterosaurs, only that it is possibly a basal rhamphorhynchoid pterosaur based on the shape of its jugal and early appearance in the fossil record. Further Reading – Pterosaur remains from the Kayenta Formation (?Early Jurassic) of Arizona . … Read more
In Depth Just like with Ankylosaurus, Nodosaurus is the type genus of a whole group of armoured dinosaurs, yet it is also one of the most poorly represented by fossil material. The nodosaurids are thought to be the ancestors of the ankylosaurids, although to have continued to thrive even in the presence of their more … Read more
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
