Phylogeography of the Mountain Tapir (Tapirus pinchaque) and the Central American Tapir (Tapirus bairdii) and the Origins of the Three Latin-American Tapirs by Means of mtCyt-B Sequences
Systems 84and Europe have been conformed to a transition family between Tapiroidea and Rhinocerotoidea (Radinsky 1967(Radinsky , 1968).However, other authors (Holbrook 1999;Colbert 2005) consider Tapiroidea as a taxon which excludes forms related to Rhinocerotoidea.Several families within Tapiroidea are well recognized by all the authors.These are the cases of Deperetellidae (Middle Eocene-Lower Oligocene from Asia; Tsubamoto et al. 2005), Lophiodontidae (Lower and Upper Eocene from Europe and Middle Asian Eocene; McKenna and Bell 1997), Lophialetidae (Middle-Upper Asian Eocene; McKenna and Bell 1997), and Helaletidae (Lower Eocene-Middle Oligocene from North America and Upper Eocene-Lower Oligocene from Asia)
