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 is thought to represent an ancient ancestor to the opossums that live in North America today.
