Matheronodon provincialis has been identified as a member of rhabdodontids - a group of herbivorous bipedal dinosaurs - from the late Campanian period about 84 to 72 million years ago. They were descendants of the iguanodontian dinosaurs from the Upper Jurassic.
What this means is that perissodactyls and artiodactyls (which counted among the mammalian megafauna of prehistoric times) both evolved from a common ancestor, which lived only a few million years after the demise of the dinosaurs at the end of the Cretaceous period, 65 million years ago.
