  • 摘要: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.
