Fusulinid.
The Cherry Canyon formation contains the youngest representatives of the fusulinid Parafusulina, the species in the lower part being the same as those in the underlying Brushy Canyon formation. It contains ammonoids at several horizons, but only the South Wells limestone member in the upper part contains diagnostic genera, such as Waagenoceras.
