"Dinos A to Z: Parasaurolophus" introduces Parasaurolophus, a duck-billed ornithopod dinosaur known for its long, hollow head crest. The video explains dinosaur classification, Greek word origins, and paleontology vocabulary while exploring fossil discovery by William Parks in Alberta, Canada, in 1922. It highlights scientific inquiry as paleontologists study how the crest may have been used for sound, communication, temperature control, or display. Additional facts cover herbivore diet, body size, scales, movement on two and four legs, herd behavior, and life during the Late Cretaceous more than 75 million years ago. This educational dinosaur overview supports life science, earth science, prehistoric life, and vocabulary development commonly aligned with elementary science curricula.
