South America of the Cenozoic, as described by G. G. Simpson as "the Splendid Isolation" lost world, shows how alternative structures of megafaunas could have been. Here a study on crocodilian dominated predatory faunas:

A new combined‐evidence phylogeny of Toxodontidae (Mammalia, Notoungulata): exploring the radiation and reconstructing hypothetical ancestors
Toxodontidae represents a major extinct radiation of South American native ungulates, but persistent polytomies in morphological phylogenies have masked its evolutionary history. To address this, we ...
