Well over 15,000 bones have been excavated from this Jurassic excavation site. There are many thousands more awaiting excavation and study. It was designated a National Natural Landmark in October 1965.[1]
All of these bones, belonging to different species, are found disarticulated and mixed together. Perhaps this strong concentration of mixed fossilised bones is due to a "predator trap". No scientific consensus has been reached yet and debates continue to the present day.[2][3]
