Edmontosaurus is one of the largest Hadrosaurids. It has over 60 rows of teeth, forming a tooth plate, so that some specimens have over 1,000 teeth. This specimen is 12m long, which is the largest among specimens of this genus in the world. In addition, it was reconstructed with over 90% of the real skeleton, which is the highest proportion of genuine material among the specimens. This specimen of Edmontosaurus has three bite marks on its tail that were probably caused by carnivorous dinosaurs. Other scars may be caused by mating competition within species or diseases, etc.
