First-Ever Madagascar Dolphin Fossil Discovered

single fossilized backbone is the first evidence on record that dolphins once swam around the waters of ancient Madagascar, scientists say.

The fossil backbone, or vertebra, dates to between 5 million and 9 million years ago during the late Miocene epoch, and belongs to a previously unknown and still unnamed species of dolphin, the researchers said.

"This exciting discovery marks the first fossil cetacean [a group including dolphins, whales and porpoises] from Madagascar," said study lead researcher Karen Samonds, an associate professor of biological sciences at Northern Illinois University.
