Crataeomus was a small, heavily armoured ankylosaur that lived during the Late Cretaceous period, between 83.6 and 72.2 million years ago. This compact herbivore measured approximately 2.5 metres in length and weighed around 350 kilograms, making it one of the smaller members of the ankylosaur group. Fossils of Crataeomus have been discovered across several European locations, particularly in Austria, suggesting it was well-adapted to the island environments that characterised Late Cretaceous Europe.

Like other ankylosaurs, Crataeomus was built like a living tank, with a low-slung body covered in bony plates and spikes for protection against predators. Its four sturdy legs supported its heavily armoured frame as it moved slowly across the landscape, browsing on low-growing plants. The dinosaur's small head was equipped with a beak-like mouth perfect for cropping vegetation, whilst rows of small teeth helped process tough plant material.

Crataeomus lived in a world where Europe consisted of numerous islands separated by shallow seas. This island environment may have influenced its relatively small size compared to ankylosaurs from other continents - a phenomenon known as island dwarfism. Despite its diminutive stature, Crataeomus was still a formidable creature, with its extensive armour providing excellent protection against the various predatory dinosaurs that shared its habitat.

As a herbivore, Crataeomus would have fed on ferns, cycads, and early flowering plants that grew in the warm, humid climate of Late Cretaceous Europe. Its low browsing height meant it rarely competed directly with taller herbivorous dinosaurs, allowing it to occupy its own ecological niche in these ancient island ecosystems.

What made Crataeomus distinctive?

Crataeomus was distinguished by its compact size and heavily armoured body covered in bony plates and defensive spikes. Its relatively small stature compared to other ankylosaurs, combined with its robust build and protective armour, made it well-suited to its European island habitat.

Behaviour

Crataeomus likely lived in small groups, slowly moving through forest undergrowth whilst feeding on low-growing vegetation. When threatened, it would have relied on its heavy armour for protection, possibly crouching down to protect its vulnerable belly whilst presenting its spiky back to predators.

Fun Facts About Crataeomus

Crataeomus is one of the few ankylosaurs known from Europe, making it particularly important for understanding how these armoured dinosaurs spread across the globe.
The small size of Crataeomus may have been an adaptation to living on islands, where limited resources often lead to smaller body sizes in animal populations.
Crataeomus lived alongside other unusual European dinosaurs, including the tiny sauropod Magyarosaurus, in what was essentially a 'lost world' of island-dwelling giants.
The bony armour plates of Crataeomus were embedded directly in its skin, creating a flexible but incredibly tough protective covering.
Crataeomus would have been one of the last ankylosaurs to live in Europe before the mass extinction event that ended the age of dinosaurs.

Discovery

Crataeomus was first described by Emanuel Bunzel in 1859. The original fossils were discovered at Austria.

Crataeomus FAQ

What did Crataeomus eat?

Crataeomus was a herbivore that fed on low-growing plants including ferns, cycads, and early flowering plants. It used its beak-like mouth to crop vegetation and small teeth to process tough plant material.

How big was Crataeomus?

Crataeomus was approximately 2.5 metres long, 1 metre tall at the hip, and weighed around 350 kilograms. This made it one of the smaller ankylosaurs, roughly the size of a large cow.

When did Crataeomus live?

Crataeomus lived during the Late Cretaceous period, between 83.6 and 72.2 million years ago. This was near the end of the age of dinosaurs, shortly before the mass extinction event.

Where was Crataeomus found?

Crataeomus fossils have been discovered in Europe, particularly in Austria. During the Late Cretaceous, this area was part of a series of islands separated by shallow seas.

How do you pronounce Crataeomus?

Crataeomus is pronounced 'cra-TAY-oh-mus', with the emphasis on the second syllable. The name comes from Greek words meaning 'strong body'.

What does Crataeomus mean?

Crataeomus means 'strong body' in Greek, referring to its heavily built, armoured physique that was characteristic of ankylosaurs.

How fast could Crataeomus run?

Crataeomus was likely a slow-moving dinosaur due to its heavy armour and short legs. It probably moved at a walking pace, relying on its protective plates and spikes rather than speed to avoid predators.

What type of dinosaur was Crataeomus?

Crataeomus was an ankylosaur, specifically belonging to the Nodosauridae family. These were heavily armoured, plant-eating dinosaurs known for their defensive capabilities.

Was Crataeomus related to birds?

Crataeomus was not closely related to birds. As an ankylosaur, it belonged to the ornithischian dinosaurs, whilst birds evolved from theropod dinosaurs, which were saurischians - a completely different group.

How many Crataeomus fossils have been found?

Crataeomus is known from limited fossil remains, primarily discovered in Austria in the 19th century. Like many European dinosaurs from this period, the fossil record is somewhat fragmentary but sufficient to understand its basic characteristics.
