In Depth Like Ornithocheirus, Anhanguera had rounded crests on both the tip of its snout and lower jaw. Also the jaws broadened towards the tip with the sharp thin teeth pointing outwards in what is often referred to as a rosette. This arrangement greatly increased the ‘catch area’ for Anhanguera as it flew over the … Read more
In Depth Tanycolagreus has been dubbed a run of the mill kind of Jurassic predator. Small and lightweight, Tanycolagreus probably focused its attentions on hunting smaller dinosaurs that were too difficult for larger predators to live on. However the holotype specimen is of a three meter subadult, with further referred material indicating a size approaching … Read more

In Depth Although known from only a single partial skull, Nemegtosaurus is quite a find as titanosaurid dinosaurs are often only known from post cranial remains. However another titanosaurid called Opisthocoelicaudia is also known from the same Formation as Nemegtosaurus, and this one is only known from post cranial remains. This has led some to … Read more
In Depth Mansourasaurus is a genus of titanosaurian sauropod dinosaur that lived in North Africa during the late Cretaceous. The discovery of Mansourasaurus was significant in itself because North African fossil beds often do not yield remains of larger dinosaurs like sauropods. This is partly because the harsh arid conditions of North Africa will often … Read more
In Depth Hypacrosaurus means ‘near the highest lizard’, and in this context the ‘lizard’ was actually the dinosaur Tyrannosaurus, one of the largest dinosaurs in the ecosystems of late Cretaceous North America, but only about a third larger than Hypacrosaurus in the largest individuals (twelve meters for large individual Tyrannosaurus compared to nine meters for … Read more
In Depth First discovered in 1998 when a road construction uncovered the remains, it took a team of palaeontologists all the way to 2012 to publish a description about this dinosaur. Yueosaurus is regarded as being a basal ornithopod dinosaur, the fifth known from Asia and the most Southern at the time of its discovery. … Read more
In Depth The lightly built skull of Abrosaurus (which is the inspiration for the name ‘delicate lizard’) clearly indicates that it was a macronarian sauropod, similar to genera such as Brachiosaurus and Camarasaurus. Camarasaurus in particular has been considered to be a very close relative of Abrosaurus because they both seem to represent basal (primitive) … Read more
In Depth The first Masiakasurus remains were described in 2001, and a second set of remains were recovered in 2011. This has allowed some of the original gaps including the premaxilla to be included with the overall morphology. The most striking feature of Masiakasaurus is the way the front teeth point forward and out of … Read more
