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.
