Summary
[edit]DescriptionJurassic National Monument 2019.jpg |
Jurassic National Monument, at the site of the Cleveland-Lloyd Dinosaur Quarry, well known for containing the densest concentration of Jurassic dinosaur fossils ever found, is a paleontological site located near Cleveland, Utah, in the San Rafael Swell, a part of the geological layers known as the Morrison Formation. Well over 15,000 bones have been excavated from this Jurassic excavation site and there are many thousands more awaiting excavation and study. It was designated a National Natural Landmark in October 1965. The John D. Dingell, Jr. Conservation, Management, and Recreation Act, signed into law March 12, 2019, named it as a national monument. All of these bones, belonging to different species, are found disarticulated and indistinctly mixed together. It has been hypothesised that this strong concentration of mixed fossilised bones is due to a "predator trap", but any kind of definitive scientific consensus hasn't been reached yet and debates still continue to the present day. Unfortunately I arrived only to learn that it was closed for the season, so I explored the surrounding area. I'll return next year to see the visitor center. |
