Abstract

The productid brachiopod Antiquatonia coloradoensis occurs commonly in lower Middle Pennsylvanian rocks representing open-bay, shelf-lagoon, and shelf-margin marine facies and extending from the Eastern Great Basin, through the Southern Rocky Mountains, southern and central Midcontinent, to the southern and eastern Appalachian Basin. This study demonstrates that Antiquatonia coloradoenesis is biostratigraphically diagnostic with a temporal range of late Morrowan through Atokan. Its ancestor was A. morrowensis (Mather) and its descendant was A. hermosana (Girty).
