On Moral Creek on the Buda limestone the Eagle Ford laminated fine sand shale, partly then limestone, and limy sandstone. The whole is upfold sharp at not far. Many of the paper tray layers are replete with (ganoid) scales, long and slender teeth and occasional fish bones. Other layers are crowded with small Ostrea like Oysters, while one of the thicker sandstones has small and large fragments of Inoceramus latistatus (is conjugated). It is an unmistakable Colorado assemblage. Whitney and Brinton both dog out a single species fades from the Brushita into the Colorado. The disconformity therepre creates considerable if a time break. The actual contact here is covered over by Talus. The presence of sand and heterotus indicate shallow water, and in higher comminuted fish matter also shows orare orrall. Probably the deposits re- present a depth of around 50 feet; saw no building up of the bottom, nor channeling.
