Fusulinid and Conodont biostratigraphy of the Beeman formation (Pennsylvanian), Sacramento Mountains, New Mexico
G.P. Wahlman and J.E. Barrick
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 Desmoinesian- 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.
