Hypacrosaurus’ name in Greek means “near the highest lizard.” It got its name because it was almost as large as the iconic Tyrannosaurus Rex. Hypacrosaurus was discovered in 1913 in Alberta, Canada. Paleontologists date Hypacrosaurus 67 million years back to the Late Cretaceous Period.
Until the discovery of eggs, hatchlings, and nests in the 1990s, Hypacrosaurus was known as an obscure genus. This dinosaur has a hollow crested skull and duckbill snout. Neural spines project from its vertebrae and are five to seven times taller than each vertebra. The Hypacrosaurus was roughly thirty feet long and weighed over four tons. Hypacrosaurus walked on two legs and four legs and stuck to a plant-based diet.
