Taxonomy: Prototheria Through Soricomorpha


Keep in mind that this is a partial list only, though fairly complete at the family level of modern taxa. A complete classification of modern mammals can be accessed (and downloaded) at the Smithsonian's Mammal Species of the World. Some taxa now extirpated from our region of interest are included if they were present historically. For general orientation, some taxa not covered in class are included. You are responsible for the taxa in bold font, including their place within the taxonomic hierarchy and their common names (there will be additions as we cover the different groups in lecture). The links to the field guide accounts of various taxa are from the "North American Species" of the Smithsonian National Museum of Natural History. The symbol indicates an extinct taxon. Classification and presentation of extant forms (order to genus) is from Wilson and Reeder (2005). Higher classification ranks are a mixture of traditional and more recent.

The taxonomy at the higher ranks is in a state of flux due both to new knowledge and to the introduction of cladistic methodologies. As such, there is no universally accepted higher classification at the moment. If you remain active in vertebrate biology, be prepared to keep tuned into current practices.
