On the Danish mainland there is a old clayquarry near the city of Gram. Claylayers from the Neogene period, 15 to 6 milion years old are exposed. The site is a typelocality. The clay and silt layers contains a lot of glauconite (mineral).
There are many facilities at the quarry. You can wash your fossils, clean your shoes, and you can look at your finds under the microscopes. You also can borrow shovers and tools. Inside the building there is an exhibition about fossils from this quarry. There is also a small shop. To enter the quarry you have to pay 50 Danish crowns per person (including the museum). For more information please visit the site http://www.grammus.dk (in Danish). In 2005 a new museum was opened next to the quarry. Here you can see many finds and also a whale skeletton.
Every certain period, the upper metre of the quarry is removed to allow access to fresh layers. At that time the chances for finding nice fossils is the greatest. For the dates of the digging visit the museum website, or contact the museum.
The quarry is suitable for children and quite large. You will have to dig to find the fossils, on the surface nothing can be found. In summer the quarry can be very hot. When the ground is wet, the clay is very sticky.

You can also find shark teeth (i.e. Lamna sp.), imprints of sea urchins, and crabs. Various microfossils like foraminifers, bryozoans and ostracods can also be found here. You can only fiind the microfossils when using a sieve. Fossils of fishes, whales, seals or seaturtles are very rare. This is one of the few places in Denmark where a Megalodon tooth has been found.
