BRITISH geologists are among an international team which has found the fossilised remains of a 130 million-year-old dinosaur complete with wrinkles on its hide and muscle remains. Derek Briggs of Bristol University and Philip Wilby of the British Geological Survey discovered the fossilised soft tissue from the bird-like dinosaur Pelecanimimus polyodon in limestone deposits in central Spain. It is only the second time that mineralised dinosaur soft tissue has been found.
