The megatherioid sloths from the Santa Cruz Formation (Santacrucian Age; early-middle
Miocene, Patagonia, southernmost South America) occupy basal positions in the most …

A developmental model, based upon murine rodents, has been proposed by Kavanagh et
al.(2007) to explain lower molar proportions in mammals. We produce a clade-wide …

Tooth size variation within fossil assemblages can be associated with intra-or interspecific
variation, functional, developmental, and geographical factors, and/or sexual dimorphism …

A three‐dimensional geometric morphometric approach was employed to examine shape
variation in laser‐scan generated models of lower second molars and its relationship to diet …

Barstovian (medial Miocene) mammalian faunas from the Texas Gulf Coastal Plain
contained four apparently sympatric species of rhinoceroses: the common forms Aphelops …

Abstract† Prospaniomys is a basal octodontoid recorded in the early Miocene in Patagonia
(Argentina; Colhuehuapian SALMA). Nearly complete cranial and mandibular remains …

Molar teeth of both Tertiary and Quaternary representatives of the family Antilocapridae were
examined using mesowear and light stereomicroscopy microwear. Taxa from the Central …

Among the Strepsirrhini, molar size does not exhibit a consistent dietary signal when body
mass is used to size-adjust molar dimensions. This observation is also true for anthropoid …

This report is the first to identify the presence of the extinct ground sloth Glossotherium
tropicorum from Pleistocene-aged tar pit deposits in Trinidad. G. tropicorum is known …

Sexual dimorphism (SD) is extremely common in species that have reproductive roles
segregated into separate sexes, and it has been recognized in several mammalian …
