Abstract

The midgut of a new specimen of Typhloesus wellsi (Melton and Scott) from the Bear Gulch Member (Namurian, Montana) contains a complete, well-preserved apparatus of Kladognathus Rexroad. The apparatus comprises 2 Pa, 2 Pb, 1 Sa, 4 Sb, 4 Sc, and 2 M elements. Kladognathus and Oulodus angulatus (Hinde) are the only members of the Prioniodinida of which complete, well-preserved bedding plane assemblages are known. The arrangement of elements in these assemblages suggests that the prioniodinid Bauplan was similar to that of ozarkodinids.
