Taxonomic list comments:based on discussion of Tedford et al. 1987, this is above the Martin Canyon Beds sensu stricto, which includes the Merycochoerus Quarry (see), and is equivalent to "horizon D" of Matthew Galbreath implies that Merychyus elegans of Schultz and Falkenbach 1947 ("M. paniensis" referred of Loomis 1924) from near "Pawnee Butte" is from the Martin Canyon equivalent shown in his fig. 8 specimen counts for Insectivora and Rodentia based on Wilson, other taxa on Galbreath 1953 generically determinate NISP 333 Galbreath 1953 indicates the presence of a "Merychippus" - grade form and of a chalicothere, both omitted by later authors; Galbreath does indicate that the chalicothere may be from younger sediments; Coombs 1998 describes Moropus material from "Martin Canyon," but this may be from Merycochoerus Quarry |
