We note the occurrence of the Late Cretaceous teleostean genus Thryptodus from the Lincoln Limestone Member (upper Middle Cenomanian) of the Greenhorn Limestone in Russell County, Kansas. The specimen, here referred to Thryptodus cf. T. zitteli Loomis, is represented by fused premaxillae. The specimen is noteworthy because it marks the oldest record of the genus.
