Fossielenexpeditie Portlantis
During this expedition on the Maasvlakte beach, fossil hunter Walter Langendoen explains how to search for archaeological and paleontological treasures.
When new land was created by pumping sand from the deep North Sea seabed, these remains of ancient life ended up on the Maasvlakte beach. Walter lives in Hellevoetsluis and searches for fossils on the Maasvlakte beach every day. His collection now consists of thousands of finds, including hyena droppings, mammoth bones, vole teeth, and much more. During the expedition, Walter examines your finds so that you know what you have found.
Put on your boots!
Prior to the expedition, participants will receive a brief explanation of how to proceed when searching for fossils. During the expedition, you will walk along the beach and the waterline. Wear boots or other suitable shoes. The trip lasts over two hours. There are no toilets on the beach, so please keep this in mind.
The fossil expedition is not suitable for very young children. In general, children from the upper grades of primary school onwards will connect sufficiently. Do you still want to participate with young children? Then ensure there are plenty of distractions.
