Pterosaurs In October, a partial Mesadacylus wing was discovered in the Kingsview Quarry of Colorado. This find marks the first time that a Morrison pterosaur has been found at more than one site in the formation.Foster, J. (2007). "Mesadactylus ornithosphyos." Jurassic West: The Dinosaurs of the Morrison Formation and Their World. Indiana University Press. pp. 159-160.
