Brachylagus coloradoensis Ramos 1999

Referred Specimens —See Appendix 1.

Description —The two specimens identified as Brachylagus coloradoensis are similar to B. idahoensis , but both have a weakly developed posterointernal reentrant and a posteroexternal reentrant that extends only between one-third and two-thirds across the tooth ( Fig. 4d). As such, these specimens are consistent with those identified as B. coloradoensis from Porcupine Cave ( Ramos, 1999b).

Discussion —Prior to this report, B. coloradoensis was known only from several localities of Irvingtonian or unknown age within Porcupine Cave ( Ramos 1999b, Barnosky 2004, Barnosky and Hopkins 2004, Baxter, 2004; age assignments from Barnosky et al. 2004). Its occurrence in Cathedral Cave extends both its geographic and chronologic ranges.
