This is not a natural group, but some of the smaller clades are, for example, Eutriconodonta and Amphilestheria. “Triconodonts” were abundant in Laurasian landmasses during the Jurassic and to a lesser degree during the Cretaceous. In contrast, the South American fossil record is sca

We recognize that we are still in the early stages of development and that much of what we know about Mesozoic South American mammals is likely to be drastically altered by finds in the continent or underrepresented
