Looking for the origin of the Rhinocerotoids.
[sciencythoughts.blogspot.com]
Both morphological and molecular studies support the idea that Rhinocerotoidea and Tapiroidea form a monophyletic group Ceratomorpha. The Ceratomorphs have abundant, diverse fossil records in the Cainozoic; however, extant Ceratomorphs are reduced to five genera and on the brink of extinction. Furthermore, despite a long research history and numerous fossils, the phylogeny and evolutionary history of the Ceratomorpha still remain contentious. Previous phylogenetic analyses have either focused on Tapiroids or Rhinocerotoids without the combination of both groups. Analyses that have contained both Tapiroids and Rhinocerotoids are still limited in taxa and character selection, so that relationships within Ceratomorpha were not well resolved and many controversies still remained.
