* [[Cleveland-Lloyd Dinosaur Quarry]], Utah: First excavated by geologists from the University of Utah in the late 1920s. [[William Lee Stokes]] led an expedition from Princeton in 1939. During the Jurassic, the quarry was likely an ephemeral pond, where dinosaurs gathered and died due to severe drought.<ref>{{cite web |last1=Gates |first1=Terry |title=The Late Jurassic Cleveland-Lloyd Dinosaur Quarry as a Drought-Induced Assemblage |url=https://pubs.geoscienceworld.org/sepm/palaios/article-abstract/20/4/363/100047/The-Late-Jurassic-Cleveland-Lloyd-Dinosaur-Quarry |publisher=PALAIOS |access-date=19 June 2024}}</ref> Their bodies were reworked by seasonal flooding events, which also added other partial carcasses from elsewhere.<ref>{{cite journal |last1=Peterson |first1=Joseph E. |last2=Warnock |first2=Jonathan P. |last3=Eberhart |first3=Shawn L. |last4=Clawson |first4=Steven R. |last5=Noto |first5=Christopher R. |title=New data towards the development of a comprehensive taphonomic framework for the Late Jurassic Cleveland-Lloyd Dinosaur Quarry, Central Utah |journal=PeerJ |pages=e3368 |doi=10.7717/peerj.3368 |date=2017|volume=5 |doi-access=free |pmid=28603668 |pmc=5463971 }}</ref> ''[[Allosaurus fragilis]]'' is by far the most common dinosaur at this site, making it a model organism for studies of paleobiology in basal theropods. The rare theropods ''[[Stokesosaurus]]'' and ''[[Marshosaurus]]'' specimens were also first discovered here.
* [[Dinosaur National Monument]], Utah: First excavated by Earl Douglas working for the [[Carnegie Museum of Natural History|Carnegie Museum]] in 1909 with the purpose of finding sauropods from the Morrison Formation for public display. Monument also has fossilized dinosaurs from the [[Cedar Mountain Formation]].
