It's not too often that you pick up a pebble and find the fossilized brain of a dinosaur that lived millions of years ago, but one man did and his finding is sweeping the minds of researchers and scientists everywhere.
It was about 12 years ago when fossil hunter Jamie Hiscocks uncovered a rusty, brown rock from the glow of his flashlight while perusing a beach in Sussex, England. Immediately drawn and wondrous of the specimen, he brought it to the attention of Martin Brasier, a paleobiologist from the University of Cambridge.
"I noticed there was something odd about the preservation," Hiscocks said, "and soft tissue preservation did go through my mind. Martin realized its potential significance right at the beginning."
The rock went through a series of examinations, including a computed tomography (CT) scanner for a closer look at the tiny details. It turned out that the detailed images revealed the remains of a prehistoric animal's brain thought to be an iguanodon-like dinosaur that roamed the Earth around 133 million years ago during the Early Cretaceous period.
The dino is said to have likely died in or near a body of water, which ultimately kept it submerged and buried in sediment that helped preserve its tissue.
Still, the theory has yet to be finalized until further research is conducted, as some researchers aren't totally convinced it's a dinosaur brain. Guess you can say this finding isn't quite set in stone after all!
