The Morrison Formation is a distinctive sequence of Late Jurassic sedimentary rock that is found in the western United States, which has a wide assortment of taxa represented in its fossil record, including dinosaur fossils in North America.

[ 3 ] [ 4 ] In the mid-1980s, the site quickly became recognized as an important location containing possibly the oldest metazoan fossils in North ...
