Abstract: Abstract Among extant hoofed mammals, only elephants and tapirs exhibit a true proboscis. We investigated the development of cranial characters potentially associated with the presence of a short proboscis in tapir species, following a comparative… read more here.

Abstract: The Litopterna is an extinct clade of endemic South American ungulates that range from Paleocene up to late Pleistocene times. Because of their unique anatomy, litopterns are of uncertain phylogenetic affinities. However, some nineteenth century… read more here.
