In Depth Although not as well known as Pakicetus and Ambulocetus, Rodhocetus is nonetheless important to the study of how whales evolved from land animals. Rodhocetus is but one of a slowly but steadily growing number of transitional fossil genera, but in Rodhocetus the change can actually be seen across the species as well. … Read more
In Depth Didelphodon acquired its name because of its similar dentition to a modern day opossum, which in turn has indicated a matching diet of insects and small animals. Its body morphology also suggests adaptation for burrowing, a good survival tactic when you consider the predatory dinosaurs of its time. As an ancient marsupial, Didelphodon … Read more
In Depth Metapterodon is a genus of creodont that lived in Africa during the early Miocene. A former species of Metapterodon, M. schlosseri, has now been assigned to its own genus, Falcatodon.

In Depth Most nimravids were relatively small cat-like mammals that ranged between one and two metres in length, but Quercylurus was a giant when compared to these, something which leads to the popular comparison of Quercylurus being the size of a brown bear. This size would make Quercylurus comparable to some of the larger creodont … Read more
