Here's an unusual sight: a mysterious skeleton jutting out of a melting iceberg off the coast of Newfoundland:
The six pictures show what looks like a brown rib cage and spinal column, slightly bent, sticking out of a crust of ice.
But researchers throughout Canada, Greenland and Norway are unable to determine the origin of the skeleton, said Garry Stenson, a marine mammal scientist with the federal Fisheries Department.
"It's definitely unusual," Stenson said today. "It's not something that I've encountered before."
His colleagues have been debating whether the carcass belongs to a bearded seal, a walrus or a beluga whale. But without the actual specimen in his hands, Stenson said he can't resolve the mystery.
