Crittendenceratops was a horned ceratopsian dinosaur that roamed the ancient landscapes of what is now Arizona during the Late Cretaceous period, approximately 83.6 million years ago. This remarkable creature holds the distinction of being the first dinosaur from the Fort Crittenden Formation to receive a formal scientific name, marking an important milestone in our understanding of North American dinosaur diversity.
As a ceratopsian, Crittendenceratops possessed the characteristic features that made these dinosaurs so distinctive - a large bony frill extending from the back of its skull and prominent horns. It walked on four sturdy legs and had a robust build typical of plant-eating dinosaurs. The single known species, C. krzyzanowskii, was named in honour of paleontologist Tomasz Krzyzanowski.
Like all ceratopsians, Crittendenceratops was a dedicated herbivore, using its sharp beak and rows of teeth to slice through tough plant material. Its powerful jaws would have been well-suited to processing the ferns, cycads, and early flowering plants that dominated the Late Cretaceous landscape. The dinosaur's impressive frill and horns likely served multiple purposes, from species recognition to defence against predators.
The discovery of Crittendenceratops has provided valuable insights into the diversity of horned dinosaurs in the American Southwest during the Campanian stage of the Late Cretaceous, filling important gaps in our knowledge of ceratopsian evolution and distribution.
What made Crittendenceratops distinctive?
Crittendenceratops displayed the classic ceratopsian features of a large bony frill and prominent facial horns. Its skull structure shows characteristics typical of centrosaurine ceratopsids, with a relatively short frill compared to other ceratopsian groups.
Behaviour
As a herbivorous ceratopsian, Crittendenceratops likely lived in herds and used its impressive horns and frill for display and defence. It would have spent much of its time foraging for vegetation, using its powerful beak to strip leaves and shoots from plants.
Discovery
Crittendenceratops was first described by Sebastian Dalman and colleagues in 2016. The original fossils were discovered at Fort Crittenden Formation, Arizona, USA.
Crittendenceratops FAQ
What did Crittendenceratops eat?
Crittendenceratops was a herbivore that fed on the plants available during the
Late Cretaceous period. It would have used its sharp beak to strip vegetation and its rows of teeth to slice through tough plant material like ferns, cycads, and early flowering plants.
How big was Crittendenceratops?
Crittendenceratops was a medium-sized ceratopsian, measuring approximately 5 metres in length and standing about 2 metres tall at the hip. It weighed roughly 2 tonnes, making it a substantial but not gigantic member of the horned dinosaur family.
When did Crittendenceratops live?
Crittendenceratops lived during the
Late Cretaceous period, specifically during the late Campanian stage approximately 83.6 million years ago. This places it in the latter part of the age of dinosaurs, several million years before the mass extinction event.
Where was Crittendenceratops found?
Crittendenceratops was discovered in the Fort Crittenden Formation in Arizona, USA. This location in the American Southwest has provided important insights into
Late Cretaceous dinosaur diversity in North America.
How do you pronounce Crittendenceratops?
Crittendenceratops is pronounced 'KRIT-en-den-SAIR-ah-tops'. The name breaks down into 'Crittenden' (after the formation where it was found) and '
ceratops' meaning horned face.
What does Crittendenceratops mean?
Crittendenceratops means 'Crittenden horned face'. The name combines 'Crittenden' (referring to the Fort Crittenden Formation where it was discovered) with the Greek '
ceratops' meaning horned face, a common ending for ceratopsian dinosaur names.
How fast could Crittendenceratops run?
The running speed of Crittendenceratops is not well established from current fossil evidence. As a large, four-legged herbivore, it likely moved at a moderate pace similar to other ceratopsians, probably capable of short bursts of speed when threatened.
What type of dinosaur was Crittendenceratops?
Crittendenceratops was a ceratopsian dinosaur, specifically a member of the family Ceratopsidae. These were the large horned dinosaurs characterised by their bony frills and facial horns, and Crittendenceratops belonged to the centrosaurine group within this family.
Was Crittendenceratops related to birds?
Crittendenceratops was not directly related to birds. As an ornithischian dinosaur, it belonged to the 'bird-hipped' group, but this is misleading - modern birds actually evolved from theropod dinosaurs in the saurischian group. Crittendenceratops and birds shared a common dinosaur ancestor but evolved along separate lineages.
How many Crittendenceratops fossils have been found?
The exact number of Crittendenceratops fossils is limited, as it was only formally described in 2016. The known remains come from the Fort Crittenden Formation in Arizona, representing the first dinosaur material from this formation to receive a scientific name.
