Parksosaurus was a small ornithopod dinosaur that lived around 72 million years ago during the Late Cretaceous period in what is now Alberta, Canada. This nimble herbivore belonged to a group of plant-eating dinosaurs that walked primarily on their hind legs, making them quite different from the massive four-legged duck-billed hadrosaurs that dominated the landscape at the time.
Measuring approximately 2.5 metres in length and standing about 80 centimetres tall at the hip, Parksosaurus was roughly the size of a large sheep. Its lightweight build and long legs suggest it was built for speed, likely using its agility to escape from predators like Albertosaurus and Daspletosaurus that shared its environment. The dinosaur had a relatively long tail that would have helped it balance whilst running.
As a herbivore, Parksosaurus fed on the ferns, conifers, and flowering plants that grew in the warm, humid climate of Late Cretaceous Alberta. Its small, leaf-shaped teeth were well-suited for cropping vegetation, and it likely spent much of its day foraging for food whilst remaining alert for danger.
What makes Parksosaurus particularly significant to palaeontologists is that it represents one of the few well-preserved non-hadrosaur ornithopods from the very end of the Cretaceous period in North America, providing valuable insights into the diversity of plant-eating dinosaurs just before the mass extinction event.
What made Parksosaurus distinctive?
Parksosaurus had a small, lightly-built frame with long, slender legs adapted for running. Its small head contained rows of leaf-shaped teeth perfect for processing plant matter, and its long tail helped provide balance during locomotion.
Behaviour
Parksosaurus was likely a swift runner that relied on speed and agility to escape predators in the forests and floodplains of Late Cretaceous Alberta. It probably lived in small groups, foraging for low-growing vegetation whilst maintaining constant vigilance for approaching threats.
Discovery
Parksosaurus was first described by Charles Mortram Sternberg in 1937. The original fossils were discovered at Horseshoe Canyon Formation, Alberta, Canada.
Parksosaurus FAQ
What did Parksosaurus eat?
Parksosaurus was a herbivore that fed on the plants available in
Late Cretaceous Alberta, including ferns, conifers, and early flowering plants. Its small, leaf-shaped teeth were perfectly designed for cropping and processing vegetation.
How big was Parksosaurus?
Parksosaurus was a small dinosaur, measuring about 2.5 metres long and standing roughly 80 centimetres tall at the hip. It weighed approximately 45 kilograms, making it about the size of a large sheep.
When did Parksosaurus live?
Parksosaurus lived during the
Late Cretaceous period, approximately 72.2 million years ago. This was very close to the end of the age of dinosaurs, just a few million years before the mass extinction event.
Where was Parksosaurus found?
Parksosaurus fossils were discovered in the Horseshoe Canyon Formation in Alberta, Canada. This formation has been a rich source of
Late Cretaceous dinosaur fossils since the early 20th century.
How do you pronounce Parksosaurus?
Parksosaurus is pronounced 'PARKS-oh-SORE-us', with emphasis on the first and third syllables. The name flows quite naturally once you break it down into its component parts.
What does Parksosaurus mean?
Parksosaurus means 'Parks' Lizard', named in honour of William Parks, a prominent Canadian palaeontologist who made important contributions to dinosaur research in the early 1900s.
How fast could Parksosaurus run?
While we don't know the exact speed of Parksosaurus, its long, slender legs and lightweight build suggest it was built for speed and could likely run quite fast when escaping from predators.
What type of dinosaur was Parksosaurus?
Parksosaurus was an ornithopod dinosaur, specifically belonging to the family Thescelosauridae. Ornithopods were a diverse group of primarily bipedal, plant-eating dinosaurs.
Was Parksosaurus related to birds?
No, Parksosaurus was not closely related to birds. As an ornithischian dinosaur, it belonged to a completely different branch of the dinosaur family tree from the theropods that gave rise to modern birds.
How many Parksosaurus fossils have been found?
Parksosaurus is known primarily from one well-preserved specimen that includes most of a skeleton with a partial skull. This relatively complete fossil has provided palaeontologists with good insights into this small ornithopod's anatomy and lifestyle.
