Introduction: Pleistocene Vertebrate Sites


Each Pleistocene fossil locality (site) has an account. Usually a general description of the site and a list of the taxa identified from the site is given. Open sites that were treated by Morgan and Lucas (2003, 2005) have been given minimal treatment; the original publications give considerably more detail and there is little sense in my plagiarizing their work beyond the bare minimum. Each locality also has a literature section that includes authors who are cited in the text of the taxon account or faunal list, as well as sometimes those otherwise pertinent to the site.

Each site is mapped if sufficient data to do so are available; placement of a site is only approximate. Blancan-age sites are shown with a yellow-centered dot; Irvingtonian-age sites with a green-centered dot; and Rancholabrean sites are noted with a red-centered dot. Originally, sites dated only as Pleistocene also received a red-centered dot; however, this is deemed to be misleading, and such red-centered dots are slowly being replaced with dark-blue-centered dots. Where both Irvingtonian and Rancholabrean or Blancan and Irvingtonian remains are present at a site, the colored portion is divided between the two. In a few cases, records have been rejected and the site to which the taxon was assigned shown with a light-blue-centered dot. Where a reasonable approximation of the locality of a site cannot be made, a black dot is placed in the center of the dot's color field. Usually such dots will be placed near the center of the county involved (some taxa are cited only as Grand Canyon; in those cases, the dot will be placed toward the center of the canyon).

The "Sites" link on the menu will take you to a complete list of links to the various sites.

Where the taxonomy has changed, the currently accepted names are listed. Synonyms that have been used regionally for fossil taxa are given in the taxon accounts. Taxa represented in the UTEP Paleobiology Collection that have either not appeared in the literature, have had changes from a published account, or have appeared only in lists without being attributed, are indicated by the UTEP acronym.

Taxa of higher taxonomic level than genus (e.g., subfamily or family) may be listed in a site account but normally will not have a taxon account.
