Spider is 20 million years old

Dr David Penny of University of Manchester has described a spider, a species from family filistatidae,that was trapped and preserved in amber 20 million years ago. He used the droplets of blood in the specimen to determine the age. Dr Penny thinks the spider was climbing a tree when it was hit by flowing resin and got trapped. He first saw the fossil during a visit to Museo del Amber Dominicano , In Puerto Plato in Dominican Republic.
