Did You Know? 15 Incredible Udanoceratops Facts

Here are some Udanoceratops facts that will tell you about the excavation site, family, and everything else that you need to know about these fascinating creatures!

Udanoceratops is a dinosaur species that was first discovered in Mongolia. The holotype specimen of this dinosaur of the cretaceous period is an almost complete skull that was excavated from a site called Udan Sayr. This site, in fact, also provides the name of the genus!

This new discovery was placed under the family of Leptoceratopsidae due to the type of skull that was observed. In spite of the scarcity of fossil remains, many features of the genus have been identified due to the resemblance the skull bears with other herbivorous members of the family. While the teeth less parrot like beak can look odd, it helps in the snapping of large plants and in turn, also adds to the considerable weight. Did you know that Udanosaurus is also the largest known ceratopsian dinosaur!

Udanoceratops Interesting Facts

How do you pronounce 'Udanoceratops'?

The name of the dinosaur Udanoceratops would be pronounced as 'oo-dahn-oh-serra-tops'.

What type of dinosaur was a Udanoceratops?

The Udanoceratops was a leptoceratopsid dinosaur from the cretaceous period. This member of the Ceratopsia order has typical features such as a herbivorous diet.

In which geological period did the Udanoceratops roam the earth?

The geological period during which the Udanoceratops tschizhovi (Sergei Kurzanov) tread the surface of the earth is said to be around the cretaceous period, which dates back to around 100 - 66 million years ago! The other terms for this timeline would include the late Santonian (upper cretaceous) or early Campanian period.

When did the Udanoceratops become extinct?

The Udanoceratops became extinct around 65 to 66 million years ago when the face of the earth met with a catastrophic collision with a meteor.

Where did a Udanoceratops live?

While the exact climatic and environmental conditions that were prevalent during the time are unknown to us, it can be gathered from the diet of this frill faced species of dinosaurs that they would have enjoyed living around lush, green grasslands and forests!

What was a Udanoceratops's habitat?

Since the fossil remains and specimens have only been found in modern day Mongolia, this species is assumed to have been endemic to the land. Similar leptoceratopsid specimens that have been found in places such as North America have been given a different classification.

Who did a Udanoceratops live with?

It is hardly possible to be able to tell the behavioral patterns of the species from the horn face skull of this species. Although, since these dinosaurs are understood to have been herbivorous in nature, it may be concluded that in spite of the scary looking jaw configuration and the range of frills on the face, Udanoceratops (Kurzanov) may have been a genus that thrived in groups!

How long did a Udanoceratops live?

The average lifespan of the Udanoceratops genus is not known since not much research could be held on the basis of the discovery of the skull fossil alone.

How did they reproduce?

Dinosaurs are known to be oviparous, which means that Udanoceratops (order Ornithischia) reproduced through laying eggs. Isn't it fascinating to imagine how huge the eggs of such a gigantic species of dinosaurs may have been!

Udanoceratops Fun Facts

What did an Udanoceratops look like?

The characteristic features of the order Ornithischia, as you can see from the fossil remains that have been found from the Udan Sayr site, include a strong, long lower jaw, short upper jaw, and horn like. The front limbs of this new dinosaur species are estimated to be less long, and in turn, are not even used for running, however, we only see them on all fours in illustrations because paleontologists believe that this new dinosaur species most of their time on all limbs to minimize strain on the hips.

One of the other features is the frill covered head, which gives us something to both be scared of and amused by!

Length of the Udanoceratops' hind legs is more than the front limbs.

How many bones did a Udanoceratops have?

The only notable specimen of the Udanoceratops that has yet been discovered is an almost complete skull. The range of observations and theories about the size and nature of the species are derivations from the research held on the skull. Since the entire skeletal figure is yet to be found, no content is available that can tell us the total number of bones that the Udanoceratops had in its body.

How did they communicate?

While no content is available regarding the call or sound of the species Udanoceratops tschizhovi (Kurzanov) species (order Ornithischia), it may be assumed from the giant size of these dinosaurs that they might have had a heavy, loud call!

How big was a Udanoceratops?

The length of an average Udanoceratops is said to be in the range of 13 ft (4 m). As you can imagine, this species was quite long, however, the height is assumed to have been short in comparison. In fact, the Udanoceratops tschizhovi (Kurzanov) is the largest leptoceratopsid dinosaur that has yet been discovered.

How fast could an Udanoceratops move?

The speed at which the Udanoceratops could move is a matter of speculation. It is assumed that although these dinosaurs spent most of their days on all four, short legs, they used only the hind legs for running from predators. It is quite tough to imagine or assume that the largest leptoceratopsid dinosaur to ever have to tread the face of the earth would also be the fastest.

How much did an Udanoceratops weigh?

The weight of this member of the Ceratopsia (meaning horn face) family from the Campanian cretaceous period, as estimated through the discovery of its skull, is about 1500 lb (50 kg). It is hardly a secret that the length of the body, strong lower jaw, and large face added to the face of this ginormous species!

What were the male and female names of the species?

There are no distinct names for the two sexes of this previous native of Udan Sayr (Mongolia), and hence, we refer to them as the male Udanoceratops and female Udanoceratops. In fact, there is no research that would suggest any classification between the features of the two sexes of Udanoceratops.

What would you call a baby Udanoceratops?

Since dinosaurs were oviparous, the juvenile Udanoceratops would be called hatchlings, as tough as it is to associate such a name with such a large animal!

What did they eat?

Based on the strong lower jaw and lack of teeth, it is assumed that the diet of these ceratopsian dinosaurs was strictly herbivorous.

How aggressive were they?

While the family of Ceratopsia (meaning horn face) can look quite intimidating due to the upper portion of the head, which is covered in frills and horn like projections, these large dinosaurs were actually herbivorous and did not have teeth! While the large size of the Udanoceratops could have easily been deadly to small animals of the Campanian period in Udan Sayr, they were not predatory or aggressive!

Did you know...

The name of the site where the fossil remains of the Udanoceratops (Kurzanov) were found is also the inspiration behind the name of the dinosaur species.

The Leptoceratopsidae family is known for a small upper jaw, and strong, heavy lower jaw.

This relatively new member of the Leptoceratopsidae family is known to have had a head covered in frills and horns.

The name Udanoceratops is derived from the site in which the holotype specimen was found in Mongolia.

What is the size of Udanoceratops's skull?

The size of the Udanoceratops (Kurzanov) skull that was discovered in Mongolia, particularly in the site called Udan Sayr, was 23.6 in (60 cm). Since the skull was almost complete, paleontologists were able to conclude that this Ceratopsia was the largest to ever be discovered.

State information about the beaked mouth of Udanoceratops?

The beaked mouth of the Udanoceratops dinosaur (Kurzanov) and the lack of teeth prove that the species was herbivorous. The strong lower jaw, and the parrot like beak, in turn, are estimated to have evolved over time so that this dinosaur species was capable of breaking plants and other foliage.
