Fossil and Mo-Clay Museum

Special Exhibit

New exhibit at the Fossil and Mo-Clay Museum opens June 1, 2021

In the mo-clay layers can be found tree trunks from a subtropical forest that existed about 55 million years ago. Where the forest was located is unknown, but the fossils tell of the primeval forest's fascinating flora and fauna. Where Mors is today used to be a sea, so all of the plant matter was transported there via the water that covered the area. The well-preserved birds and insects found in the mo-clay likely came from the same forests as the tree trunks. Very rare traces of insect larvae have been found in the wood and leaves, made by bark beetles and other woodboring beetles and possibly by the larvae of sawflies and butterflies.

The quality of preservation of the wood can vary, and the best-preserved pieces are the ones that have been silicified. The well-preserved pieces of wood have growth rings, and even the cell structure is perfectly preserved, allowing scientists to determine if for instance the tree was a conifer or a broadleaf. All this and much more will be expanded upon in the placards made for this renewal of the Fossil and Mo-Clay Museum's permanent wing on fossilized plants from the mo-clay.

Denmark's largest fossil is a tree trunk measuring 9.5 meters in length that was found in the Ejerslev mo-clay pit in December 2017, and this amazing piece of wood will now be exhibited in its full glory alongside other impressive trunks in a giant new showcase.

You can try your hand as a fossil hunter yourself in the mo-clay pit at the museum, and you can also join a guided fossil hunt every weekday during the high season.
