It was a small mammal by modern standards but big by Late Cretaceous standards, being about a 1 feet long (0.3 meters) and 5 kilograms (11 lb). As an endotherm, it needed to eat on a regular basis to produce the energy needed to regulate its body. Being a small animal in a time of large dinosaurs, it was prey for theropods like young Tyrannosaurus, young Dakotaraptor, Acheroraptor, Anzu, and Pectinodon, reptiles like Borealosuchus, and Palaeosaniwa, and the pterosaur Quetzalcoatlus. 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. As an ancient marsupial, Didelphodon is thought to represent an ancient ancestor to the opossums that live in North America today. The teeth have specialized bladelike cusps and carnassial notches, indicating that the animal was a predator; the jaws are short and massive and bear enormous, bulbous premolar teeth which appear to have been used for crushing. Analyses of a near-complete skull referred to Didelphodon show that it had an unusually high bite force quotient (i.e. bite force relative to body size) among Mesozoic mammals, suggesting a durophagous diet. However, its skull lacks the vaulted forehead of hyenas and other specialized bone-eating durophagous mammals, indicating that its diet was perhaps a mixture of hard foodstuffs (e.g. snails, bones) alongside small vertebrates, carrion, and possibly plants.
Didelphodon will appear in Saurian.
