Formation:Pozas Member:Botijas
Stratigraphy comments: The formation consists of volcanic breccia, tuff, volcanic sandstone interbedded with ash-flow tuff, lava, and limestone lenses, one of which is the Botijas Limestone Member consisting of massive to thick-bedded limestone and calcarenite (Krushensky and Schellekens, 2001). The Botijas Limestone Member was deposited in a shallow marine environment containing abundant rudists of middle Campanian age (S. Mitchell, pers. comm., 2005).
