Frogs fill in post-Gondwana picture

The positions of landmasses after the breakup of Gondwana during the late Mesozoic and early Paleogene are highly debated, especially the configurations of the Indian and Australian plates around the newly opening Indian Ocean. In a new study, the paleogeographic and genetic distributions of a group of frogs called Natatanurans were used to test the various post-breakup models — and the results bring additional clarity to the post-Gondwana puzzle.

South American fossils offer revised view of Gondwana assembly

Fossils of a known age have been found for the first time in rocks in Brazil that, although long-studied, had previously eluded scientists’ attempts to pinpoint their age. The discovery of the marine animals dates the rocks to 550 million years ago, researchers say, offering important insights into the geological evolution and timing of the assembly of the former supercontinent Gondwana.
