Taxonomic list comments:appears to be at the level of LACM 5857 based on literal interpretation of scale in sections given by Kelly 1990 and Kelly et al. 1991 almost entirely from CIT 180, but some Kelly 1990 records may be from UCMP V-6103 or V-87155; CIT 217 of Golz and Lillegraven 1977, which yielded only "Artiodactyla indet." NISP 1324+ record of ? Hyaenodontidae indet. is omitted by Kelly 1990 "cf. Sespedectes sp." is omitted by Kelly 1990 not clear what "cf. Hemiacodon sp." is "Reithroparamyinae indet." is omitted by Kelly 1990 |
