0.9 cm Edmontosaurus tooth

The 0.9 cm tooth of Edmontosaurus annectens is in a very good state of preservation and comes from the Hell Creek Formation in Montana. Edmontosaurus annectens was a large, herbivorous dinosaur that lived in North America during the Late Cretaceous period. With a length of up to 13.4 meters and a weight of over 6,200 kg, it was one of the largest hadrosaurs. The distinctive, duckbill-like jaw was equipped with more than 2,000 constantly growing teeth, which Edmontosaurus used to crush even tough plants such as leaves, needles and twigs. As a highly developed herd animal, it lived in large groups, which offered protection from predatory dinosaurs such as the Tyrannosaurus rex. Fossil finds show that Edmontosaurus was caring and raised its young together in large colonies. The herd structure increased the chances of survival, especially for young animals, and favored the joint incubation and feeding of the offspring. Edmontosaurus mainly moved on all fours, but was able to stand up to reach higher food. Its skeleton does not show any pronounced defensive weapons, but older animals protected the herd with their massive appearance. Evidence has been found that individual animals survived attacks by Tyrannosaurus rex, as healed bite marks show. Translated with DeepL.com (free version)
