This hadrosaur tooth has excellent preservation, including serrations that would have helped the dinosaur grind down plant material. This tooth would make a great addition to any dinosaur collection.
All our fossils are consolidated with paraloid b72, to preserve for future generations as is standard procedure within all museums. No repairs or restoration to this fossil.
The Judith River Formation of Montana is believed to have two types of hadrosaur, Probrachylophosaurus and Brachylophosaurus, and to preserve an evolutionary transition with the former slowly evolving into the latter. Both dinosaurs were related to the famous Maiasaura and reached a length of 9 meters. Brachylophosaurus in particular is famous for having well-preserved specimens known, including evidence of individuals with cancerous tumors.
The Judith River Formation of Montana dates to the Campanian stage of the Late Cretaceous, around 75-80 million years ago. Notable dinosaurs from this formation include the tyrannosaurs Gorgosaurus and Daspletosaurus, the hadrosaur Brachylophosaurus, and the ankylosaur Zuul.
