A scientist has described a spider that was trapped and preserved in amber 20 million years ago.Palaeontologist Dr David Penney, of the University of Manchester, found the 4cm long by 2cm wide fossil during a visit to a museum in the Dominican Republic.
Since the discovery two years ago, he has used droplets of blood in the amber to reveal the age of the specimen.
It is thought to be the first time spider blood has been found in amber and scientists hope to extract its DNA.
