St. George Dinosaur Discovery Site (Split Tracklayer)Hunt A. P., Lucas S. G. (2006)Glen Canyon - Moenave - Whitmore Pointamong the lowest of the 25 regional track-bearing layers, 4-15 cm above MTL layer

Most of the Moenave Formation is the Dinosaur Canyon Member. In the Moenave type section, near Tuba City, Arizona, all of the Moenave section is Dinosaur Canyon Member, as it is throughout the Moenave outcrop belt along the Echo Cliffs and Ward's Terrace of northern Arizona. However, north of the Grand Canyon in Arizona and in southwestern Utah, the upper part of the Moenave Formation is lacustrine strata. T
