Caption: The richest marine reptile fossil bed along Africa's South Atlantic coast has been dated at 71.5 million years old. A new study uses carbon isotope dating to determine the first precise age for this bed, and ties the western coast of Africa, where it split from South America 130 million years ago, to 30 million years of global geologic records.
