Desmoceratidae and Silesitidae (ammonitida) from the Aptian - Albian of Antarctica

Aptian-Albian Desmoceratidae and Silesitidae of James Ross Island, Antarctica are described. Desmoceratid Puzosiinae are represented by Parasilesites IMLAY, Pseudosilesites EGOIAN, Feruglioceras LEANZA, Umsinenoceras KENNEDY et al., and Silesitidae by species of Neoastieria EGOIAN, Piatnitzkyceras M...
