Late Cenozoic Bryozoa from diamictites of Cape Lamb, Vega Island, Antarctic Peninsula
Bryozoans were found in upper Cenozoic diamictite debris that crops out at the southwestern tip of Cape Lamb, Vega Island. The diamictite is the youngest deposit on the island and richly composed of foraminifers, brachiopods and scallops. The foraminifera assemblage recovered from the Cape Lamb diam...
