Alaska, Pliocene to Pleistocene (Ice Age), ca. 100,000 to 20,000 years old. A matched pair of fossilized lower left and right molars from a mammoth. Remarkably well preserved, these nearly identical massive gnashers present with a flat occlusal surface each holding twenty-six vertical black wavy lines of the enamel ridges and diagonal distal sides curving down to the long shag-like roots and one thick root separated from the others towards the slightly slanted mesial face. The number of enamel ridges identifies this mammoth as the woolly mammoth of Alaska, while the curved shape of the molars and split root tells us that these are lower teeth. As a mammoth grows six sets of molars in its 60-year lifespan, its approximate age when the molars fall out can be determined by the size of the lost tooth. This molar measures nearly 7.5" long, indicating the mammoth was most likely 30 to 50 years old when the tooth was lost. The glistening mottled quartz on the edge of the mesial and occlusal sides further enhances the beauty of this ancient beast! Size: 11.25" L x 11.25" W (28.6 cm x 28.6 cm); 8" H (20.3 cm) on included custom stand.
The original chemicals of the teeth have been replaced in the fossilization process with quartz (silica) and other minerals, which may give a clue to its place of origin. For example, fossils found in the Wind River Formation in Wyoming have often been replaced by silica. Mammoth teeth are highly specialized, some of the largest grinding teeth in the animal kingdom, adapted to crush woody vegetable matter in ancient forests.

Condition
One molar has a broken bottom section of about 1.5" on its two back roots. Light abrasions to the outside facing surfaces of both. Surface wear commensurate with age. Earthen deposits and small white and tan pebbles wedged throughout highlight the well defined roots with nice contrasts of color! Overall in excellent condition.
