Description

The Flowerpot formation is very similar in geology to and was once thought to overlie the San Angelo formation, sometimes only being able to be differentiated by what layer underlie the unit in the area of study, both being mostly made up of red shales. Though unlike San Angelo, the depositional environment of the terrestrial shales of the Flowerpot formation seemed to be immediately adjacent along with the formation of deltas and floodplains being present. Due to this, stream deposits from the formation can directly be traces to the nearby basin. The formation lacks plant fossils, however there are records of carbonaceous streaks.
