Dinosaur senescence: a hadrosauroid with age-related diseases brings a new perspective of “old” dinosaurs

Abstract Senile vertebrates are extremely rare in the fossil record, making their recognition difficult. Here we present the largest known representative of the Late Cretaceous hadrosauriform Gobihadros mongoliensis showing features of cessation of growth indicating attainment of the terminal size....
