Texas

A caver dropped into a hole in the limestone of Comal County, Texas, put his face into the underground stream at the bottom, and found the streambed paved with bones.

John Young photographed what he could see and sent the images to John Moretti, a palaeontologist at the University of Texas at Austin, expecting an identification and possibly a polite thank you. Moretti asked to come and look himself. What followed, written up in a paper published in Quaternary Research, is the first palaeontological study ever made of a Texas water cave.
