Pg. 28. Royer marble. Marine deposition in Arbuckle uplift began with Reagan sandstone, and Upper Cambrian formation with abundant fauna. Over this comes Royer marble, a previously unnamed Lower Ozarkian formation, about 500 feet thick, that was included by Taff in basal part of his great Arbuckle limestone. The fauna found in this formation invaded from west of Rocky Mountains by way of Marathon basin of western Texas. Neither Middle nor Upper Ozarkian deposits occur in Oklahoma. The remainder of Taff's Arbuckle limestone is assigned to Canadian Period. It includes Lower, Middle, and Upper Canadian.
