Parasaurolophus was a relatively bulky dinosaur and is often depicted as standing upright on its two thick muscular back legs with a thick pointed tail and oval-shaped body. Parasaurolophus had a long narrow head with large eyes on a mid-length neck, a hard beak and a narrow snout with pebbly textured skin and uniform tubercle-like scales.
Parasaurolophus is most recognizable by its large and elaborate cranial crest that researchers believe could have measured as long as 6 1/2 feet long.
This dino’s name means “like Saurolophus,” which is another crested dinosaur.
But it turns out these two aren’t that similar: Saurolophus’s headgear was solid;
Parasaurolophus’s crest was hollow. So experts believe they used them for different reasons.
