This is a genuine unerupted JUVENILE fossil dinosaur tooth of an Edmontosaurus annectens. It is rare as it has no feeding wear yet on the crown. Edmontosaurus annectens was the predominant hadrosaur species that can be found in the Hell Creek Formation or Northwestern U.S.A., former home to Tyrannosaurus rex, dromaeosaurs ("raptors") and the horned dinosaurs like Triceratops. Excellent for a comparative collection of adult - baby fossil dinosaur teeth.
For its astonishing array of dangerous and large prehistoric predator fossils, no place has captured more attention or has been featured on television more than Hell Creek! This area is known to many as "the Valley of the T. rex!". The "duck-billed" Hadrosaurs and the "horned" dinosaurs like Triceratops were common prey for many large meat-eating dinosaurs of the famed region.
