The petrosal and bony labyrinth of extinct horses (Perissodactyla, Equidae) and their implications for perissodactyl evolution [PDF]

open access: yesPeerJ
Perissodactyla, or odd-toed ungulates, are represented today by 16 species of rhinoceroses, tapirs, and horses. Perissodactyls were much more diverse in the past, having a rich fossil record spanning from the earliest Eocene (~56 Ma) to recent, including

Rhinocerotidae and Chalicotheriidae (Perissodactyla, Tapiromorpha) [PDF]

open access: greenGeodiversitas, 2016
ABSTRACT Here we describe mandibular, dental, and postcranial remains referable to Rhinocerotidae and Chalicotheriidae (Perissodactyla) originating from the vertebrate localities of Kucukcekmece East and Kucukcekmece West, in Thrace (European Turkey). The four rhinocerotids recognized comprise the early diverging Ronzotherium sp.

Perissodactyla of the Sespe Eocene, California [PDF]

Convergence of Afrotherian and Laurasiatherian Ungulate-Like Mammals: First Morphological Evidence from the Paleocene of Morocco. [PDF]

open access: yesPLoS ONE, 2016
Molecular-based analyses showed that extant "ungulate" mammals are polyphyletic and belong to the two main clades Afrotheria (Paenungulata) and Laurasiatheria (Euungulata: Cetartiodactyla-Perissodactyla).
