The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. 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. By the end of the Devonian , several of these g

I 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.
