Uinta C | "massive sandstone, fine-grained" | TMM | two isolated specimens are from nearby TMM 41871 and TMM 42185, which are in the same unit Westgate 1990 reports NISP 101 excluding rodents and indeterminate records; later publications report 288, for a total of 389 plus two species lacking counts; Westgate 1988 reports "nearly 700" and Westgate 1990 "over 700," and I believe the discrepancy is due to counting indeterminate specimens said to be Uinta C | |
