Summary:
Pg. 13-18, fig. 3, pl. 1. Lazy Bend formation. In this report [Parker County, north-central Texas], beds cropping out along Brazos River upstream from Dennis Bridge to beyond Lazy Bend are placed in Lazy Bend formation. Includes (ascending) Hill Creek member (with Dennis Bridge limestone bed at base), Steussy member, and Brannon Bridge member. There is no continuous type section of formation; knowledge of succession is gained by mapping key beds between separated outcrops, and type sections are established member by member. Underlies Grindstone Creek formation. Age is Pennsylvanian. Classification in this paper does not go above formation rank.
