World’s first ever fossilised dinosaur brain found

We may finally find out just how clever dinosaurs were, after scientists discovered a 133-million-year-old-dinosaur brain.
The incredible find was discovered on a Sussex beach as part of a larger fossil.
While to the untrained eye, the fossil looks just like a common stone, amateur fossil collector Jamie Hiscocks saw it in a rock pool in East Sussex and passed it onto expert palaeontologists.
That discovery was back in 2004, but after years of research, scientists now say they think it contains the first fossilised dinosaur brain ever found.
The findings were made public at the annual gathering of the Society for Vertebrate Palaeontology in Utah.
Researchers found tiny traces of brain matter from the thin protective tissue which covers the outside of the brain.
After examining it in intricate detail, they have announced it belongs to a dinosaur like the Iguanodon.
However because the fossil was found near to other rocks which are around 133 million years old, it is likely this is a relative of the Iguanodon, which roamed the land millions of years earlier.
The Iguanodon won the hearts of millions of children and parents as the lead character in the Disney movie Dinosaur, which follows an orphaned Iguanodon who befriends a family of lemurs and helps them to survive a meteor.
While researchers now say more study is needed before they can draw any more conclusions from this piece of brain matter, so far they think the dinosaur was at least as clever as modern-day crocodiles.
Previous theories about the intelligence of dinosaurs have relied heavily on a mixture of speculation and comparisons with modern-day birds and reptiles, thought to be dinosaurs’ closest living relatives.
However this discovery, and the ongoing research, could finally give us some more definitive answers.
While casts of the inside of dinosaur brain cases have been found previously, this is the first time any fossilised soft brain tissue has been discovered.
It is believed this dinosaur toppled into a lake or a swamp, with its head coming to rest upside down. The acidic conditions and lack of oxygen will have preserved some of the brain, while the rest of the cavity filled with other material.
Paleontologist David Norman, of the University of Cambridge worked on the fossil. He said: “This is the nearest I suspect we’re ever going to get to the whole brain.”
