Ictaluridae—CatfishRegional Pleistocene distribution of Ictalurus sp.

Catfish of various species occur natively in New Mexico, mostly in the eastern drainages and into the Rio Grande. The Blancan beds in the vicinity of La Union produced a single specimen (a fragment of pectoral spine, UTEP 33-60, Fig. 1) that Vanderhill (1986) thought closely resembles that of the channel catfish (Ictalurus punctatus). Vanderhill (1986) took its presence as a sign that permanent water, probably in the form of large streams, was present.
