Kiel, S. and Amano, K. (2010) Oligocene and Miocene Vesicomyid Bivalves from the Katalla District, Southern Alaska. Veliger, 51 (1). pp. 76-84.

Abstract

Six fossil vesicomyid species from the Katalla district in Alaska are described and illustrated, and three of them are described as new. Calyptogena katallaensis, Archivesica marincovichi, and Archivesica sp. are from the Oligocene Kulthieth Formation, and Archivesica redwoodia and Adulomya spp. A and B are from the lower Miocene Redwood Formation. The Oligocene Calyptogena katallaensis represents the oldest record of Calyptogena, which had previously been traced only into the late Miocene. Archivesica redwoodia shows an unusual mix of characters, including a Calyptogena-like hinge dentition, pallial sinus, and the lack of a nymphal ridge.
