HIGHLIGHTS
GONDWANAN PERSPECTIVES: PALEONTOLOGICAL STUDIES IN ANTARCTICA AND ITS BIOGEOGRAPHIC CONNECTION WITH SOUTH AMERICA (PART 3)
- LATE EOCENE DINOFLAGELLATES FROM MARAMBIO ISLAND
Based on cyst events, the Submeseta Formation's age in betwween 36.7 and 34.1 My (Priabonian, late Eocene), confirming that the unit does not extend into the Oligocene.
- DIVERSE UPPER PALEOCENE FLORA FROM MARAMBIO ISLAND
A new unbiased collection is dominated by ferns (Cladophlebis and Sphenopteris), followed by Atherospermataceae, Lauraceae, Moraceae, and Winteraceae.
- AN EARLY CENOZOIC BIOGEOGRAPHICAL BARRIER FOR TERRESTRIAL MAMMALS
The Weddell Line is proposed as a new biogeographical barrier that acted as a sweepstakes route between East and West Antarctica during early Paleogene times.
