Researchers have finally figured out what happened to a group of marine animals that died out on the ancient supercontinent Gondwana — and the finger points squarely at climate change.
At the time of the extinction, the area near the South Pole was home to Gondwana, which comprised parts of what is now Africa, South America, Australia, Antarctica, the Indian subcontinent and the Arabian Peninsula. Gondwana formed around 600 million years ago with the breakup of supercontinent Pangaea and began to split apart around 180 million years ago.
To get to the bottom of this cold case, the team reanalyzed hundreds of fossils belonging to the Malvinoxhosan biota, paying particular attention to the location, depth and geological properties of the rocks that each fossil was found in. This enabled them to piece together a timeline of what happened to the region by sorting it into layers, kind of like"sorting through the layers of a cake," according to the statement.
