Tyrannosaurus rex dominated its ecosystem by singularly exploiting the roles of mid- and large-sized carnivore as it grew up. Despite its iconic status as the king of dinosaurs, Tyrannosaurus rex biology is incompletely understood. Here, we examine femur and tibia bone microstructure from two half-grown T. rex specimens, permitting the assessments of age, growth rate, and maturity necessary for investigating the early life history of this giant theropod. Osteohistology reveals these were… CONTINUE READING
