In Depth When fossils of this dinosaur were originally described as Lambeosaurus laticaudus, the estimated size of the species was given as between fifteen and sixteen and a half meters long, something that causes inaccurate size quotations for Lambeosaurus to this day even though larger individuals of this genus are around the nine meter mark. … Read more
In Depth Certainly one of the more difficult dinosaur names to pronounce, Mnyamawamtuka is a genus of titanosaur that lived in Africa during the Cretaceous. The holotype of Mnyamawamtuka is recognised as one of the most complete titanosaurs ever discovered. The high level of completeness may be down to the fact that this creature was … 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 Weewarrasaurus is a genus of ornithischian dinosaur that lived in Australia during the late Cretaceous. At the time of writing, Weewarrasaurus is known from only two dentaries’ (lower jaws), so precise details about this dinosaur are otherwise unknown.

In Depth Iguanacolossus acquired its name from its similarity to another dinosaur named Iguanodon. Although Iguanacolossus might not actually have been any bigger than the largest examples of Iguanodon, it might still have been the largest ornithopod plant eating dinosaur alive in North America at this stage of the Cretaceous, with the only plant eaters … Read more
In Depth Although many of the placodonts had shells only a few like Henodus and Placochelys had single shells that covered the entire body, while others like Cyamodus had two shells. Henodus has one of the most well developed single shells of all placodonts made up by a fusion of a large number of scutes … Read more
In Depth Fresnosaurus was a late Cretaceous era elasmosaurid plesiosaur that seems to have the signature feature of this group of a very long neck proportionately greater than in earlier and more primitive plesiosaur forms. Like with these other genera, Fresnosaurus was probably a specialist hunter of fish and soft bodied cephalopods like squid. Fresnosaurus … Read more
In Depth Preondactylus is another contender for earliest pterosaur although new discoveries are constantly challenging this. One feature that confirms the basal placement of Preondactylus is the short wings, since as pterosaurs evolved the wings became proportionately larger. The hind legs are also very long in relation to the total body length. The diet of … Read more
