Dinosaurs are known for their massive sizes that are the result of some of the most remarkable growth strategies in the animal kingdom. T. rex in particular is iconic for being one of the largest land predators to have ever existed, in addition to being one of the fastest-growing land predators. But we don’t know where and when in time tyrannosaurs dramatically evolved to become gigantic. Evan’s research focuses on reconstructing the life history of Tarbosaurus, a close relative of T. rex, by examining the growth history hidden inside the limb bones of several individuals at different ages. By understanding how Tarbosaurus grew, he hopes to not only understand the evolution of gigantism in tyrannosaurs but also lay the foundation for a more refined look at tyrannosaur development on a species basis.
