Which group was first formed between Dinosaur Pile-Up and Enanitos Verdes?
Enanitos Verdes Enanitos Verdes (Literally "Little green dwarfs", roughly equivalent to the English phrase "Little green men") is a rock trio from Argentina, formed in 1979 in the city of Mendoza.
Shinarump Conglomerate The early Late Triassic conglomerate called the Shinarump Conglomerate, formally the "Shinarump Member of the Chinle Formation", is a highly resistant coarse-grained sandstone and pebble conglomerate, sometimes forming a caprock because of its hardness, cementation, and erosion resistance. The Shinarump is found throughout the Colorado Plateau with significant exposures as the canyon rimrock in the vicinity of Canyon De Chelly National Monument, at the north-northeast of the Defiance Plateau/Defiance Uplift. At Canyon De Chelly the Shinarump Conglomerate was laid down upon De Chelly Sandstone-(280 Ma, an erosion unconformity of 50 my), in a region at the west foothill region of the mostly north-south trending Chuska Mountains of northeast Arizona – northwest New Mexico.
