Volcano Eruption Baked Rare Rhino Fossil

A rare fossil of a rhinoceros that roamed what is now Turkey reveals the tale of a sudden violent death—by volcano, 9.2 million years ago.
The ancient rhino’s skull and jaw have a rough surface and brittle teeth.
Paleontologist Pierre-Olivier Antoine of the University of Montpellier in France thinks that’s because volcanic rock fragments from the Cardak caldera pelted the rhino. A speeding river of ash and rock probably dismembered the animal and “baked” its skull at temperatures reaching 840ºF (450°C).
Just 2 percent of fossils are found in volcanic rock, because the heat usually incinerates organic matter. It’s even rarer to find a mammal fossil.
