Prosaurolophus was a large ornithopod dinosaur that roamed the forests and plains of North America during the Late Cretaceous period, approximately 75.7 to 74.1 million years ago. This impressive herbivore measured around 9 metres in length and stood about 3 metres tall at the hip, making it one of the substantial plant-eaters of its time.
The most distinctive feature of Prosaurolophus was its small, solid crest formed by extended nasal bones that protruded upwards just in front of its eyes. Unlike some of its relatives with elaborate hollow crests, Prosaurolophus had a relatively simple but distinctive bony prominence that gave it a unique profile amongst the ornithopod dinosaurs of the Late Cretaceous.
As a herbivore, Prosaurolophus possessed the typical ornithopod features for plant processing, including rows of grinding teeth and a beak-like mouth perfect for cropping vegetation. Its fossils have been discovered in both the Dinosaur Park Formation of Alberta, Canada, and the Two Medicine Formation of Montana, USA, indicating it was well-established across western North America.
Remarkably well-preserved, Prosaurolophus is known from the remains of at least 25 individuals, including complete skulls and skeletons. This wealth of fossil material has provided palaeontologists with detailed insights into its anatomy and lifestyle, making it one of the better-understood ornithopod dinosaurs from the Late Cretaceous period.
What made Prosaurolophus distinctive?
Prosaurolophus had a distinctive small, solid crest formed by the nasal bones that stuck up prominently in front of its eyes. This bony ridge gave it a unique profile that distinguished it from other ornithopod dinosaurs of its time.
Behaviour
Prosaurolophus likely lived in herds, as evidenced by multiple individuals found in the same geological formations. As a large ornithopod, it would have spent much of its time foraging for plants, using its specialised teeth to process tough vegetation.
Discovery
Prosaurolophus was first described by Barnum Brown in 1916. The original fossils were discovered at Dinosaur Park Formation, Alberta, Canada.
Prosaurolophus FAQ
What did Prosaurolophus eat?
Prosaurolophus was a herbivore that fed on the abundant plant life of
Late Cretaceous North America. It used its beak-like mouth to crop vegetation and had rows of grinding teeth perfect for processing tough plant material like ferns, conifers, and flowering plants.
How big was Prosaurolophus?
Prosaurolophus was quite large, measuring approximately 9 metres in length and standing about 3 metres tall at the hip. It weighed roughly 3.5 tonnes, making it a substantial ornithopod dinosaur comparable in size to a modern elephant.
When did Prosaurolophus live?
Prosaurolophus lived during the
Late Cretaceous period, specifically between 75.7 and 74.1 million years ago. This places it in the Campanian age, when North America was home to diverse dinosaur communities.
Where was Prosaurolophus found?
Prosaurolophus fossils have been discovered in North America, specifically in the Dinosaur Park Formation of Alberta, Canada, and the Two Medicine Formation of Montana, USA. These locations were once lush, subtropical environments perfect for large herbivorous dinosaurs.
How do you pronounce Prosaurolophus?
Prosaurolophus is pronounced 'pro-saw-ROL-oh-fus', with the emphasis on the third syllable. The name can be broken down into parts: 'pro' meaning before, 'sauro' meaning lizard, and 'lophus' meaning crest.
What does Prosaurolophus mean?
Prosaurolophus means 'before
Saurolophus' in Greek. This name was chosen because palaeontologists initially thought it was an ancestor or earlier relative of Saurolophus, another crested ornithopod dinosaur.
How fast could Prosaurolophus run?
Based on its size and leg proportions, Prosaurolophus could likely reach speeds of up to 25 km/h when necessary. This would have been fast enough to escape from many predators, though it probably spent most of its time moving at a much slower walking pace while foraging.
What type of dinosaur was Prosaurolophus?
Prosaurolophus was an ornithopod dinosaur, belonging to the hadrosaurid family commonly known as duck-billed dinosaurs. It was a large, herbivorous dinosaur that walked on both two and four legs, with specialised teeth for processing plant material.
Was Prosaurolophus related to birds?
Like all dinosaurs, Prosaurolophus was distantly related to modern birds, but as an ornithopod, it was not on the direct evolutionary line that led to birds. Birds evolved from theropod dinosaurs, whilst Prosaurolophus belonged to a different group of plant-eating dinosaurs.
How many Prosaurolophus fossils have been found?
Prosaurolophus is remarkably well-represented in the fossil record, with remains from at least 25 individuals discovered. These include complete skulls and skeletons, making it one of the most thoroughly understood ornithopod dinosaurs from the
Late Cretaceous period.
