Fusulinid and Conodont biostratigraphy of the Beeman formation (Pennsylvanian), Sacramento Mountains, New Mexico

Abstract

A bstrAct — Fusulinid and conodont biostratigraphic analyses date the Pennsylvanian Beeman Formation in the Sacramento Mountains of south-central New Mexico as early middle Missourian to the early to early middle Virgilian. Based on conodont data, the Desmoine-sian-Missourian boundary is in the uppermost part of the underlying Gobbler Formation, and based on fusulinid and conodont data, the Missourian-Virgilian boundary is in the upper part of the Beeman Formation.
