A Gnawing Problem: Does Rodent Incisor Microwear Record Diet Or Habitat?, Salvatore Samuel Caporale
A Gnawing Problem: Does Rodent Incisor Microwear Record Diet Or Habitat?, Salvatore Samuel Caporale
Graduate Theses and Dissertations
Dental microwear has been shown to reflect food preferences and habitat in extant vertebrates, and its analysis has been applied to fossil assemblages to infer paleodiet and paleoenvironment. Such reconstructions are, of course, only as good as the extant baseline used to infer relationships between wear pattern and diet/habitat. This study tests, through dental microwear texture analysis, the potential of modern rodent lower incisors to reveal those relationships, and evaluates the extent to which effects of diet and habitat can be parsed from the signal. Microwear texture profiles were created for individual lower rodent incisors (n=430) using confocal profilometry and …

Reconstructing The Dietary Signal Of The Primate Taxon Cercopithecoides Williamsi From The Plio-Pleistocene Caves Of South Africa, William G. Anderson, Frank L. Williams
DISCOVERY: Georgia State Honors College Undergraduate Research Journal
The taxon known as Cercopithecoides williamsi has been reconstructed as a terrestrial primate folivore from its dental morphology and heavy dental microwear. It was recovered at a number of Plio-Pleistocene caves in South Africa, including Makapansgat, Sterkfontein Member 4, Sterkfontein West Pit and Bolt’s Farm. For the purposes of corroborating or contradicting previous dietary reconstructions, six specimens of Cercopithecoides williamsi were examined and compared with the extant primate taxa Papio ursinus (n = 5), Papio cynocephalus (n = 5) and Colobus polykomos (n = 5) to provide a frame of reference, using low-magnification stereomicroscopy in conjunction with an ocular reticle …
