One of the unique parts of the Museum's exhibition T.rex: The Ultimate Predator is life-size models of a T.rex hatchling, juvenile, and adult. The three stages are shown on this bright green youth t-shirt in sizes XS to XL. Cotton blend. Machine washable.

How did a fluffy little critter turn into a massive killing machine? Every terrifying T. rex was once a helpless hatchling. And all tyrannosaurs evolved from smaller ancestors—some not much bigger than the hatchling as adults. The full tyrannosaur story spans 100 million years of evolution and includes dozens of species discovered around the world—including T. rex, uncovered in Montana in 1905 by American Museum of Natural History fossil hunter Barnum Brown. Visit this spectacular exhibition now through August, 2020.
