A decades-old museum mystery is finally solved by modern analysis.

For 70 years, two fossil “mammoth” bones sat quietly in an Alaska museum, tagged from a 1951 expedition near Fairbanks and treated as a rare clue to the last woolly mammoths in North America.
Then scientists took a closer look, and the story flipped. Isotope chemistry hinted at a marine diet, not a land grazer, so researchers dug into the records and ran ancient DNA testing.
The result was stranger than anyone expected: the fossils belonged to two different whales. Now the headline isn’t “young mammoth” at all, but a new mystery about how whale bones ended up deep in Alaska’s interior, miles from the coast.
