New trigonioid bivalves from the Early Jurasic to earliest Cretaceous of the Antarctic Peninsula region: systematics and austral paleobiogeography
New discoveries of trigonioid bivalves are documented from three areas in the Antartic Peninsula: the Fossil Bluff Group of Alexander Island, the Latady Formation of the Orville Coast, and the Byers Group of Livingston Island, South Shetland Islands. Eleven taxa are described, representing six gener...
