Where in the world

There are fragmentary bones of Leedsichthys in many museums across the world. The only complete list of institutions with Leedsichthys specimens ever published was in Dr Jeff Liston’s paper ‘The occurrence of the Middle Jurassic pachycormid fish Leedsichthys’, Oryctos Vol 9, 2010. This is a revised and updated version of that list.

If you know of any other specimens or would like us to add a link to your institution, please contact us at peterboroughmuseum.org.uk/contact
