Abstract

Denticle number per unit of length in the (P) element of contemporaneously occurring Ozarkodina excavata (Branson and Mehl) and O. tuma Murphy and Matti is a characteristic that shows that these taxa belong to two discrete species. Their morphological ranges with respect to this character do not overlap.

Ozarkodina tuma has a short range within the delta Zone (Lower Devonian) of the central Great Basin and is useful in intrabasin correlation.
