Araucariaceae macrofossil record from South America and Antarctica
Araucariaceae fossils are abundant in Patagonia and on Seymour (Marambio) and King George (25 de Mayo) islands, Antarctica. Araucariacean macrofossil suites are represented by records of 121 woods, leaves, ovuliferous scales, cones, one seed and seedlings, many of them placed in 50 formalized morpho...
