The Gray Fossil Site is a deposit of laminated clay and silt sediments laid down in an ancient lake that formed within a sinkhole. The deposit is oval in shape, covering an area of roughly 220 meters by 180 meters and ranging in depth from about 7 meters to 39 meters deep.
What type of dinosaur it belonged to is unknown, but there have been suggestions that it was from Allosaurus. "Beelemodon": Known only from two teeth found in Wyoming.
