Pterosaur fossils have been recovered from the formation. DescriptionThe two phosphorite horizons are separated in places by a yellowish sand interbed up to 1 m thick; however, they sometimes merge into a single horizon. The lower interbed or part of the integrated phosphorite horizon shows in places straight diagonal bedding, which is manifested in the orientation of almost flat pellets, pebbles, and pseudomorphs on bivalve shells. The phosphate concretions are irregular aggregates and rounded pebbles, ranging in size from several millimeters to 5–10 cm. They are dark brown or nearly black.[1] Fossil contentThe following vertebrate fossils were reported from the formation:[1] {{div col|colwidth=20em}}
