Researchers mapped out "cake-like" fossil layers belonging to a group of ancient marine creatures from the supercontinent Gondwana that mysteriously died off 390 million years ago. 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.It turns out that the so-called biota — an ancient group of water-dwelling animals — disappeared from Gondwana over a period of 5 million years because sea levels gradually lowered, a new study, published Oct. 13 in the journal Earth-Science Reviews, found. And the climate change that wiped out this animal group has disturbing parallels to the changes happening today.
