The Jurassic sea was home to the biggest species of fish ever known, Leedsichthys problematicus
This bony fish would have grown up to 16 metres in length, and is thought to have been a filter feeder, living on plankton and krill. In 2001, the most complete skeleton of Leedsichthys was discovered in the Star Pit brick quarry near Peterborough. A team of fossil experts excavated the creature, over a period of 2 years. Over 1800 bones were collected. The specimen is now part of the Peterborough Museum collections.
