Hypacrosaurus Dinosaur
The name Hypacrosaurus means ‘near the highest lizard,’ referring to its close size comparison with the Tyrannosaurus, one of the largest dinosaurs of late Cretaceous North America. While Tyrannosaurus could reach about twelve meters, Hypacrosaurus grew to around nine meters. It’s likely that Hypacrosaurus, along with similar dinosaurs, was preyed upon by Tyrannosaurus and related predators like Albertosaurus. This is supported by evidence of a large bite wound on an Edmontosaurus that healed after an attack, indicating the animal survived the encounter. With nests containing about twenty eggs, Hypacrosaurus reproduced quickly, compensating for high mortality rates. Besides tyrannosaurs, smaller predators such as troodontids would have posed dangers, especially to younger Hypacrosaurus, affecting how many reached adulthood.
The crest of Hypacrosaurus is similar to that of its relative Corythosaurus, though wider and not as high. This crest was also hollow, which confirms its establishment as a lambeosaurine hadrosaurid (the group typified by Lambeosaurus). Several theories have been made about the function of lambeosaurine head crests, though the one with the most support concerns visual display so that different species of hadrosaur can tell each other apart, probably in a similar fashion to how the differences in the forms of horns and neck frills allow different genera of ceratopsian dinosaurs to be identified.
