The member is described as a yellow-gray calcarenite 1 to 2 ft thick that lies above the Blue Hill Shale Member of the Carlile and below the Fort Hays Limestone Member of the Niobrara Formation.

The boundary is at the top of the fencepost limestone (FP) identified by the underlying. I've just come back from a trip to Yorkshire where I managed to do a little fossil hunting and was lucky enough to find this ammonite.

The problem is though is that generally the preservation in the area wasn't great and this one is clearly covered in a mudstone/ shale type of rock. Abundant peleeypods and ammonites indicate that the Juana Lopez Member is of early late Turonian age (Upper Cretaceous).

The Greenhorn Limestone or Greenhorn Formation is a geologic formation in the Great Plains Region of the United States.

It preserves fossils dating back to the Cenomanian and Turonian of the Late Cretaceous period. The formation was named for the Greenhorn Station on Greenhorn Creek in Colorado in by Grove Karl Gilbert; and it is the eponym of the Greenhorn Marine Cycle of the Country: United States.
