Abingdon Museum has an exhibition about some reptiles, fish and floaty creatures that might have been found in Jurassic times when Abingdon would have been a sea.
There are fossils and information boards describing creatures such as Ichthyosaurs, Pliasaurs, Plesiosaurs, Leedsichthys problematicus, Shastasaurs, Ammonites & Belemnites.
A large aquarium containing one large sea creature can be viewed through a VR headset. The VR headset has been popular and will be used in future with different VR films.
This weekend, the museum website https://www.abingdon.gov.uk/abingdon-county-hall-museum has details for a talk by the palaeontology professor from Portsmouth about the Pliosaurus (or Abingdon Sea Monster).
