Lithology and environment
Primary lithology:massive,lag sandstone
Includes fossils?Y
Lithology description: The Upper Meniscotherium locality corresponds to the basal lag deposit in a sandstone unit with clay-pebble lenses and unionid clams that immediately overlies and cuts into the mudstone of V71237 (UCMP locality records; also see Williamson 2001). Strait et al. 2016: "massive, moderately-indurated sandstone unit that immediately overlies the mudstone of V71237. In V71238 fossils are found as lag in apprximately 10 cm at the base of this sandstone unit and appear to represent a direct reworking of the underlying mudstone unit."
Environment:fluvial indet.
