Scientists identify fossilised dinosaur brain tissue for first time

British and Australian scientists have identified an unassuming brown pebble, found more than a decade ago by a fossil hunter in southern England, as the first known example of fossilised dinosaur brain tissue. The fossilised 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.
