Taxonomic list comments:replaces list of Williamson and Lucas 1993, which included material from East Flank and West Flank of Kimbetoh Arroyo (see) Williamson's list 16 although Williamson omits multis, they were described by Sloan 1981 following localities could be from either arroyo: LACM 5090, 5091, 5092, 5394, 5395, 5396; UALP 7631 Williamson and Lucas state that UCMP V-2811, 2813, and 3861 are in Barrel Spring Arroyo, but I consider it likely this is a lapsus Lucas et al. 1981 claim that MH "Tetraclaenodon" and "pantodont" i.d.s of Rigby and Lucas 1981 are in error a single interval of less than 8 m according to Lindsay et al. 1981 "? Procerberus sp." and new leptictid "A" are present only at Black Toe (see) "Desmatoclaenus protogonioides" and "D. dianae" of Williamson and Lucas 1993 are actually from East Flank of Kimbetoh Arroyo (see) |
