Open publisher page 49 citations

Abstract

Previously undescribed Early Pennsylvanian (Morrowan and Atokan or Derryan) platform conodonts are described from eight localities in Oklahoma, Texas, and Nevada. The 11 new species are assigned to six genera, of which Declinognathodus and Rhachistognathus are new. The new condont taxa are: Cavusgnathus spatha, C. transitoria, Gnathodus defectus, Declinognathodus nevadensis, Idiognathodus humerus, I. incurvus, Streptognathodus angustus, S. anteeccentricus, S. parvus, S. suberectus, and Rhachistognathus prima.
