Collection methods and comments
| Collection size: | 40 specimens |
| Taxonomic list comments:"40 specimens" Runningwater Fm., Red Valley Mbr., and Dawes Clay Mbr. all are superposed in the canyon: fig. 8 "Merychyus verrucomalus" Stevens 1970 from two coordinates on Sand Canyon; I presume these are from the Runningwater "Metatomarctus canavus" Wang et al. 1999: "Sand Canyon Region" "Brachycrus cf. wilsoni" of Schultz and Falkenbach 1940 is from "the upper part of the section in this canyon" (Dawes Clay?); Schultz and Falkenbach 1940 also list Merycochoerus sp. - and Schultz and Falkenbach 1941 "Ticholeptus hypsodus" - but these are of unstated provenance | |
