Hadrosaur Tapestries
Description: Roughly 76 to 75 million years ago during the Late Cretaceous period, large herds of an animal now known as Lambeosaurus congregated around the shallow rivers that ran through what is now Alberta, Canada. These beasts could be up to 31 feet long, and weigh up to 3 and a quarter tons, they would mostly walk on all fours, switching to two when speed was required, their huge tails stiffly hanging in the air behind them, making up nearly half of their length. On their heads, they sported large, flamboyant crests, the males likely sporting ones larger and more complex than those of the females.
Description: Parasaurolophus (or “near crested lizard”) was a hadrosaur, or duck billed dinosaur that lived in North America and Asia during the Late Cretaceous Period, roughly 76.5–73 million years ago. They traveled in large herds and bore a large crest on their heads that scientists believed served a dual purpose with both a species recognition symbol and as an acoustic resonance chamber. The hollow sections of the crest likely allowed them to let out range of loud noises to signal many things like sounding a warning for the rest of the herd to know that a predator is near by and to attract mates.
