Ctenacanthiform Cladodont Teeth from the Lower PermianWichita Group, Texas, U.S.A.

Abstract

Isolated teeth of Glikmanius occidentalis occur in ten vertebrate faunas in theWaggoner Ranch Formation and in one fauna in the underlying Petrolia Formation. They range in size (anteromedial-posterolateral base length) from 1.28mmto 10.15mm(n = 12). In addition to the typical teeth, one with an asymmetrical base and one possible posterior tooth (both G. ?occidentalis), and a questionable symphyseal tooth (Glikmanius?), occur in the collection.
