The view that Antarctica and South America were connected by a long causeway between
the West Antarctica (WANT) and southern South America in the Late Cretaceous through the
late Paleocene, and that terrestrial vertebrates were able to colonize new frontiers using this
physiographical feature, is almost certainly correct. One of the most intriguing
palaeobiogeographical phenomena involving the last phase of the breakup of the
supercontinent Gondwana concerns the close similarities and, in most cases, inferred sister …

The rearrangement of the Southern Hemisphere land masses through time had enormous
consequences in the climate model and biotic distribution of the Cenozoic, in particular the
separation of South America from Antarctica. Antarctica is considered the Rosetta Stone of
the paleobiogeographic and biotic evolution in the Southern Hemisphere. The book entitled
“Late Cretaceous/Paleogene West Antarctica terrestrial biota and its intercontinental
affinities” condenses the knowledge of several decades of field trips and studies carried out …
