Environment
Lithology: siliciclastic (mixed)
Taphonomic context: fluvial deposit
Habitat comments: "Local lithology is variable, although gray to white mudstone, muddy sandstone and carbonate nodule conglomerates are common"
"no significant differences were observed between the horses at Farish Ranch, Ten Mile Waterhole Creek and Buckner Ranch Site 1"
"The fossils were in sand lenses interbedded with clay ball conglomerates, in a channel fill which cuts deeply into a resistant reddish brown sandstone”
