Fossils referred to Diplotomodon date to the Late Cretaceous (Maastrichtian), roughly 72.2 to 66 million years ago. Finds come from the United States. It was a carnivore and walked on two legs.
The fossils of Diplotomodon are too incomplete for a responsible length, hip height, or weight, so those fields are left blank on purpose.
