Abstract

Niobrarateuthis walkeri, a new species of kelaenid squid, differs substantially from European kelaenids described by Naef (1922) and from the North American kelaenid, N. bonneri which was also recovered from the Niobrara Formation. The new species consists of an extended anterior spike-like rhachis and a greatly enlarged ventrally open posterior conus. Niobrarateuthis walkeri n. sp. inhabited the Niobrara Sea during late Coniacian to early Santonian time and was recovered from the basal Smoky Hill Chalk.
