Microwear in burrowing rodents


The study of microwear features on the enamel surface of mammalian teeth is widely used to reconstruct paleodiets of extinct mammals. Few of these prior studies have focused on rodents and those that did often focused on a single taxon or a few related taxa. We focused on mylagaulids and geomyids, two groups of extinct subterranean rodents present in the Great Basin during the Miocene. Knowledge of their diet will allow further investigation of the paleoecology of this peculiar family of fossil rodents.

The results of this research were presented at the annual meeting of the Society of Vertebrate Paleontology in Pittsburgh (2010) and are part of my M.S. thesis at the University of Oregon.
