New Material of Schizotheriine Chalicothere (Perissodactyla, Chalicotheriidae) from the Xianshuihe Formation (Early Miocene) of Lanzhou Basin, Northwest China

open access: yesJournal of Paleontology, 2022
A new schizotheriine mandible from the early Miocene Xianshuihe Formation in Lanzhou Basin, Northwest China is described here. Compared with other contemporaneous taxa, the lower jaw is most similar to Borissiakia betpakdalensis from Kazakhstan based on ...

The phylogeny of the Rhinocerotoidea (Mammalia, Perissodactyla) [PDF]

open access: greenZoological Journal of the Linnean Society, 1986
A new phylogeny of the Superfamily Rhinocerotoidea is proposed, based upon an analysis of shared derived characters of the skull, teeth and skeleton. Hyrachyus is considered the primitive sister-taxon of the three rhinocerotoid families (Amynodontidae, Hyracodontidae, Rhinocerotidae), and the amynodonts appear to be the sister-group of hyracodonts and ...

THE ADAPTIVE RADIATION OF THE PHENACODONTID CONDYLARTHS AND THE ORIGIN OF THE PERISSODACTYLA [PDF]

open access: bronzeEvolution, 1966
The mammalian order Condylarthra includes a heterogeneous assemblage of smallto medium-sized archaic omnivores and herbivores. Most families in the order flourished in the Paleocene and became extinct early in the Eocene. A few lineages, however, developed crucial adaptations which led to their emergence as new orders of mammals, one of which was the ...

THE EARLY EVOLUTION OF THE PERISSODACTYLA [PDF]

open access: bronzeEvolution, 1969
Perissodactyls arose from phenacodontid condylarths in the late Paleocene, in a major adaptive shift involving two functional complexes: specialization of the limbs for running, including a radical remodelling of the ankle joint that restricted lateral movement, and a change in molar cusp pattern and jaw musculature that increased transverse shear ...

The origin of Rhinocerotoidea and phylogeny of Ceratomorpha (Mammalia, Perissodactyla) [PDF]

open access: goldCommunications Biology, 2020
AbstractRhinoceroses have been considered to have originated from tapiroids in the middle Eocene; however, the transition remains controversial, and the first unequivocal rhinocerotoids appeared about 4 Ma later than the earliest tapiroids of the Early Eocene.
