Denversaurus was a heavily armoured ankylosaur that roamed the ancient landscapes of western North America during the Late Cretaceous period, between 83.6 and 72.2 million years ago. This impressive herbivore measured approximately 6 metres in length and stood about 1.5 metres tall at the hip, making it a formidable presence on the prehistoric plains.
Like other ankylosaurs, Denversaurus was built like a living tank, with its back and sides covered in thick, bony plates called osteoderms. These defensive features were embedded in its skin and provided excellent protection against the large predators of its time, including tyrannosaurs. The creature's low-slung body and wide stance made it difficult to flip over, whilst its armoured covering would have deflected most attacks.
As a herbivore, Denversaurus spent its days browsing on low-growing plants, ferns, and cycads. Its small head housed a relatively tiny brain, but its beak-like mouth was perfectly adapted for cropping vegetation. The dinosaur's teeth were small and leaf-shaped, ideal for processing plant material before swallowing.
Denversaurus was initially considered by some scientists to be the same animal as Edmontonia, another nodosaurid ankylosaur. However, detailed studies of the fossil evidence have confirmed that Denversaurus represents its own distinct genus, with unique anatomical features that set it apart from its armoured relatives.
What made Denversaurus distinctive?
Denversaurus was distinguished by its extensive armour plating covering its back and sides, consisting of rows of bony osteoderms embedded in the skin. Unlike club-tailed ankylosaurs, it lacked a tail club but had prominent spikes projecting from its shoulders and sides for defence.
Behaviour
Denversaurus likely lived in small herds or family groups, grazing peacefully on vegetation throughout the day. When threatened by predators, it probably crouched low to the ground, presenting only its heavily armoured back to attackers whilst protecting its vulnerable underside.
Discovery
Denversaurus was first described by Robert Bakker in 1988. The original fossils were discovered at South Platte Formation, Colorado, USA.
Denversaurus FAQ
What did Denversaurus eat?
Denversaurus was a herbivore that fed on low-growing plants, ferns, cycads, and other vegetation. Its small, leaf-shaped teeth were perfectly designed for cropping and processing plant material, whilst its beak-like mouth helped it select the most nutritious parts of plants.
How big was Denversaurus?
Denversaurus measured approximately 6 metres in length and stood about 1.5 metres tall at the hip. It weighed roughly 2.5 tonnes, making it a substantial but not gigantic member of the ankylosaur family.
When did Denversaurus live?
Denversaurus lived during the
Late Cretaceous period, between 83.6 and 72.2 million years ago. This places it in the final chapter of the Age of Dinosaurs, shortly before the mass extinction event that ended the Cretaceous period.
Where was Denversaurus found?
Denversaurus fossils were discovered in North America, specifically in the South Platte Formation of Colorado, USA. The dinosaur lived across western North America during the
Late Cretaceous period.
How do you pronounce Denversaurus?
Denversaurus is pronounced 'DEN-ver-SORE-us', with emphasis on the first syllable. The name is straightforward to say, being based on Denver, the capital city of Colorado.
What does Denversaurus mean?
Denversaurus means 'Denver Lizard', named after Denver, Colorado, near where its fossils were first discovered. Like all dinosaur names, it combines a descriptive element with the Greek word 'saurus' meaning lizard.
How fast could Denversaurus run?
Denversaurus could probably reach speeds of around 15 km/h when necessary. However, as a heavily armoured quadruped, it was built more for defence than speed and likely spent most of its time moving slowly whilst grazing.
What type of dinosaur was Denversaurus?
Denversaurus was an ankylosaur, specifically a member of the Nodosauridae family. These were heavily armoured, herbivorous dinosaurs that walked on four legs and were covered in bony plates and spikes for protection against predators.
Was Denversaurus related to birds?
As an ankylosaur, Denversaurus belonged to the ornithischian ('bird-hipped') dinosaurs, but this group is not directly related to modern birds. Birds actually evolved from theropod dinosaurs, which were saurischian ('lizard-hipped') dinosaurs.
How many Denversaurus fossils have been found?
Relatively few Denversaurus fossils have been discovered compared to some other dinosaurs. The limited fossil material initially led some scientists to consider it the same animal as Edmontonia, though detailed study has confirmed it as a distinct genus.
