Jose Antonio Nievas was out for a stream-side walk on Christmas Day when he stumbled across a shell that looks straight out of Jurassic Park.
After partially digging it out of the mud, the Argentine rushed home to tell his family about his discovery. “At first I thought it was a rock or a car tire,” he told Argentine newspaper La Nacion.
But was it?
Argentine paleontologists say it's probably the shell of a glyptodont, a giant prehistoric armadillo that might have looked something like this:
“There is no doubt that it looks like a glyptodont,” Alejandro Kramarz, a paleontologist with Argentina’s Bernadino Rivadavia Natural Sciences Museum, told AFP. “The animal became extinct thousands of years ago and it is very common to find their fossils in this region.”
The prehistoric mammals had big round shells and were believed to weight up to a ton.
Kramarz said he believes the shell could be 10,000 years old.
