![A girl of five discovered a 190million-year-old fish fossil while she and her family were having an ice cream on the Jurassic Coast at Charmouth in Dorset, the U.K. Helena Ashby noticed a small imprint of fish scales protruding from a pebble, and thought there may be more inside. Later a perfectly preserved Pholidophorus was inside the stone. The find was rare because dead fish tend to sink to the bottom of the sea and decompose.
