HIGHLIGHTS

GONDWANAN PERSPECTIVES: PALEONTOLOGICAL STUDIES IN ANTARCTICA AND ITS BIOGEOGRAPHIC CONNECTION WITH SOUTH AMERICA (PART 2)

- LATE JURASSIC ACTINOPTERYGIAN FISHES FROM LONGING GAP

Scales are described from the Ameghino Formation, representing the first record of Amiiformes in Antarctica and the southernmost records for both Amiiformes and Ginglymodi worldwide.

- NEW UPPER CRETACEOUS PLESIOSAUR FROM VEGA ISLAND

Elasmosaurid remains, including parts of the cranium, are described from Snow Hill Island Formation.

- BODY SIZE INCREASE IN PALEOGENE POLYDOLOPIDAE

The congruent evolutionary history between South America and Antarctic polydolopid species reinforces the idea of a single biogeographic unit comoposed of Patagonia and the Antactica Peninsula.
