Scientists from Australia and Great Britain have uncovered a modest brown pebble, excavated more than a decade ago in south England by a fossil hunter, which they have confirmed to be the first known specimen of fossilized dinosaur brain tissue.

The fossilized brain, found by fossil enthusiast Jamie Hiscocks near Bexhill in Sussex in 2004, is most likely from a species similar to Iguanodon – a large herbivore that lived during the early cretaceous period, some 133 million years ago.

In a report of their analysis in a Special Publication of the Geological Society of London, the researchers said they believed this piece of tissue was so well-preserved because the dinosaur’s brain was “pickled” in a highly acidic and low-oxygen body of water – like a bog or swamp – shortly after it died.

“The chances of preserving brain tissue are incredibly small, so the discovery of this specimen is astonishing,” said Alex Liu of Cambridge University’s department of earth sciences, who worked on its identification.
