Great Basin Mylagaulidae


Mylagaulids are abundant burrowing rodents in Miocene faunas from western North America. Recent taxonomic revisions of mylagaulids from the Great Plains suggest that their systematics may be best understood on a regional basis. Previous studies have addressed the taxonomy and evolutionary history of mylagaulids from the Great Basin, but recent discoveries of specimens, new phylogenetic data, and more detailed stratigraphic information necessitate a thorough reanalysis of their relationships and occurrences. We therefore present a revision of the systematics of the mylagaulids from the Great Basin.

The results of our research were presented at the Oregon Academy of Sciences annual meeting in Portland (2010) and are part of my M.S. thesis at the University of Oregon. The resulting paper is published in the Zoological Journal of the Linnean Society.
