Abstract

We describe the first occurrence of the Late Cretaceous pycnodont fish referred to Anomoeodus cf. A. barberi Hussakof, from the Smoky Hill Chalk Member of the Niobrara Chalk in western Logan County, Kansas. The specimen is an incomplete right prearticular tooth plate that was surface collected from the upper Smoky Hill Chalk (lower Campanian), and represents the second and the youngest occurrence of Anomoeodus from Kansas. The addition of this taxon to the fauna of the Smoky Hill Chalk increases the total number of pycnodont taxa to four, bony fish taxa to 56, and total fish taxa to 72.
