Excerpt from Systematic Revision of Fossil Prairie Dogs With Descriptions of Two New Species

For this revision, I examined over 400 fossil (pre Holocene) prairie dog Specimens and Recent samples Of five extant species. My study focussed on lower jaws with teeth because they are abundant and diagnostic as fossils. Relatively complete skulls, uncommon as fossils, were considered when avail able. Isolated teeth were only utilized when other, more complete specimens were rare or absent at a locality. Post-cranial elements were not studied.
