We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids.

davidcpowers posted a fossil in BrachiopodsI collected this Leptaena brachiopod from the red brown mudstone resting three feet above the top of the first out crop of breccia limestone. The location is above the rest-stop on highway 89 S before Riceville Rd. The formation is the lower part of the Kibbey. Leptaena Brachiopods dominate along with three types of bryozoa and crinoids. Also found clams and a part of a plant fossil. The setting was once a lagoon.
