Illustration of a juvenile Tyrannosaurus rex. Most of this restoration is mostly inspired from the models of 1-year old Tyrannosaurus from the exhibition "T.rex: The Ultimate Predator" at American Museum of Natural History, New York (2019-2021).[1] [2] and the juvenile Tarbosaurus MPC-D 107/7 (2-3 years old at death).[3] References ↑ [1] ↑ [2] ↑ Tsuihiji T et.al (2011).
