Late Ordovician jawed polychaete faunas of the type Cincinnatian region, U.S.A.

From: Journal of Paleontology | Date: May 1, 2003| Author: | Copyright information

Abstract-Late Ordovician jawed polychaete (Annelida) faunas from the type Cincinnatian region in the tri-stale area of Indiana, Ohio, and Kentucky, North America, are discussed on the basis of an extensive and unique collection of more than 50,000 wellpreserved scolecodonts. Approximately 40 to 5 0 multi-element species belonging to a dozen families are identified. Scolecodonts of polychaetes with prionognath, and particularly labidognath, type of jaw apparatus markedly dominate, whereas those of placognalh and ctenognath taxa are very rare. The most common and/or characteristic genera include ...
