On the 9th December 2017 I started volunteering at Bristol Museum and Art Gallery at their Pliosaurus! exhibition which ran from June 2017 until the 18th of February 2018. This interactive museum exhibition focused on the 8 metre long fossil of marine reptile Pliosaurus carpenteri (known as Deadly Doris the Pliosaurus! at Bristol Museum). The only known specimen of its species and a rare example of a relatively complete Pliosaur. In this article I explain more about the fossil, my volunteer role, what I enjoyed about the exhibition and what I think the impact of it has been.
