North America, Montana, late Cretaceous period, ca. 70 to 65.5 million years ago. A rare and incredibly well-preserved section of a dental battery from a duck-billed dinosaur known as an Edmontosaurus. The mandible of an Edmontosaurus contained over 1,000 miniscule teeth that moved in a side-to-side motion to pulverize and chew rough vegetal materials like conifer needles, tree bark, and angiosperms that would otherwise be inedible. This battery section contains 82 full and partial teeth of petaloid forms with crested midsections that are reminiscent of reptilian scales, and the surfaces have developed a lustrous chocolate-brown patina due to the process of fossilization. Lucite display stand for photography purposes only. Size: 8.4" L x 3.3" W (21.3 cm x 8.4 cm)

Provenance: private Hagar collection, Wildwood, Missouri, USA
