Lambeosaurus

Lambeosaurus is a genus of crested, plant-eating hadrosaurid dinosaurs from Late Cretaceous western North America. Its distinctive hollow cranial crest varied in shape among species.

Hadrosauridae: Hadrosauridae is a family of herbivorous ornithischian dinosaurs, commonly called duck-billed dinosaurs. Lambeosaurus belongs to this family of diverse, often crested herbivores.
Hadrosaurid dental battery: A hadrosaurid dental battery is a tightly packed set of replacement teeth used to grind plant material. Lambeosaurus used rows of teeth to process tough vegetation.
Lawrence Lambe: Lawrence Lambe was a Canadian geologist and paleontologist who described numerous Cretaceous vertebrate fossils. Lambe named the genus in 1923 from fossils found in Alberta.
Corythosaurus: Corythosaurus is a crested hadrosaurid dinosaur known from Late Cretaceous western North America. Its helmet-shaped crest contrasts with Lambeosaurus's taller, hatchet-shaped crest.
Lambeosaurinae: Lambeosaurinae is a hadrosaurid subfamily characterized by hollow cranial crests connected to the nasal passages. This subfamily includes Lambeosaurus and other hollow-crested hadrosaurids.
Hadrosaurid cranial crest function: Hadrosaurid cranial crest function concerns the roles of hollow skull crests in sound production, display, and recognition. The crest's internal passages may have altered calls, though its exact functions remain debated.
Dinosaur Park Formation: The Dinosaur Park Formation is a Late Cretaceous fossil-bearing rock unit in Alberta, Canada. Its fossils include major specimens assigned to Lambeosaurus.
Parasaurolophus: Parasaurolophus is a hadrosaurid dinosaur with a long, backward-projecting cranial crest. Its elongated crest offers a striking alternative to Lambeosaurus's upright crest.
Cranial crest: A cranial crest is a bony projection from an animal's skull, sometimes enlarged or ornamented. Lambeosaurus is recognized by its elaborate hollow crest.
Nasal passage: A nasal passage is an airway that carries inhaled air through the nasal cavity. Lambeosaurus's crest enclosed elongated nasal passages that shaped its skull anatomy.
