Eubrontes, a dinosaur footprint in the Moenave Formation at the St. George Dinosaur Discovery Site at Johnson Farm, southwestern Utah.
The Moenave Formation is a Mesozoic geologic formation, in the Glen Canyon Group. It is found in Utah and Arizona.
The Moenave was deposited on an erosion surface on the Chinle Formation following an early Jurassic uplift and unconformity that represents about ten million years of missing sedimentation.[1] Periodic incursions of shallow seas from the north during the Jurassic flooded parts of Wyoming, Montana, and a northeast–southwest trending trough on the Utah/Idaho border.[2] The Moenave was deposited in a variety of river, lake, and flood-plain environments, near the ancient Lake Dixie.[1]
The oldest beds of this formation belong to the Dinosaur Canyon Member, a reddish, slope-forming rock layer with thin beds of siltstone that are interbedded with mudstone and fine sandstone.[3] The Dinosaur Canyon, with a local thickness of 140 to 375 feet (43 to 114 m), was probably laid down in slow-moving streams, ponds and large lakes.[4] Evidence for this is in cross-bedding of the sediments and large numbers of fish fossils.
The upper member of the Moenave is the pale reddish-brown with a thickness of 75 to 150 feet (23 to 46 m) and cliff-forming Springdale Sandstone.[4] It was deposited in swifter, larger, and more voluminous streams than the older Dinosaur Canyon Member.[3] Fossils of large sturgeon-like freshwater fish have been found in the beds of the Springdale Sandstone.[3] The next member in the Moenave Formation is the thin-bedded Whitmore Point, which is made of mudstone and shale.[3] The lower red cliffs visible from the Zion Human History Museum (until 2000 the Zion Canyon Visitor Center) and the St. George Dinosaur Discovery Site, discovered on February 26, 2000, are accessible examples of this formation.[5]
