16.5" Wide Woolly Mammoth Mandible with M2 Molars - North Sea

This is an absolutely stunning, 16.5" wide lower jaw of a woolly mammoth, complete with a pair of beautifully preserved M2 molarss still in place. It would have come from a subadult mammoth and the molars each measure about 6.4" long. There is an unerupted M3 molar visible within the right side of the mandible.

It is in phenomenal condition with excellent bone and molar preservation, complete with exposed foramen that would have housed blood vessels and nerves. The bone is exceptionally stable and required no crack repair or restoration!

The Woolly Mammoth (Mammuthus primegenius) is the iconic Pleistocene animal. They had long hair, tusks that extended up to 9 feet, and stood about 12 feet tall. They ranged across the northern hemisphere and were one of the most abundant Pleistocene creatures.

These Pleistocene fossils are dredged up by fishing trawlers in the the North Sea between Britain and Denmark. Fishermen routinely find mammoth teeth and many ice aged fossils in their nets and given the chance that a fossil is accidentally gathered in a net is slim the sea floor is probably littered with the remains of millions of animals. The cold temperatures and low oxygen environment of the North Sea has aided in the preservation of these teeth and bones.

While these fossils have been pulled up in nets for more than a century, they were frequently discarded. It wasn't until the past two decades that this material has begun to be systematically collected and studied. By recording the locations of their finds and allowing scientists to make observations before the more common material is made available, much has been learned about the fauna that once roamed the land that now lies 30 to 150 feet below the North Sea waters.

These fossils have been submerged in salt water for over ten thousand years so they had to go through a lengthy stabilization process so they do not disintegrate. The fossils are immersed for six weeks in constantly refreshed, fresh water. They are then slowly dried, and stabilized with a museum standard conservation layer, which not only preserves the fossils, but also brings out their natural stunning coloring. This process takes around two to three months to complete.
