15 Dino-mite Cetiosauriscus Facts That Kids Will Love

Cetiosauriscus facts are all about a Sauropod dinosaur that once roamed in England.

Cetiosauriscus (Cetiosauriscus stewarti) was a long-necked dinosaur of the middle Jurassic period, that existed about 165 million years ago. The first fossil remains were found in Europe more than 100 years ago. The German paleontologist, Friedrich von Huene, in 1927, named this species of dinosaur, considering that they were similar to the Cetiosaurus. The name Cetiosauriscus refers to whale lizard-like, while the name Cetiosaurus means whale lizard. Later on, the partial postcranial skeleton of this species was excavated near Peterborough, a town in England. This new finding led to the argument that it was a new species of dinosaur and therefore, should be given a new genus name.

Much before the discovery of the holotype BMNH R.3078 in England, Friedrich von Huene, himself confirmed that the Cetiosauriscus type species had much longer vertebrae than the Cetiosaurus. The holotype BMNH R.3078 further confirmed the presence of a whiplash tail in this dinosaur species, just like that of a Supersaurus. These Sauropod dinosaur species had a herbivorous diet and were medium to large in size with about 7 t (6350.3 kg) of weight. Keep on reading to know more facts on this fascinating dinosaur.

Cetiosauriscus Interesting Facts

How do you pronounce 'Cetiosauriscus '?

Cetiosauriscus is pronounced as Set-e-os-sore-is-kuss.

What type of dinosaur was a Cetiosauriscus?

The Cetiosauriscus dinosaurs belonged to the Sauropoda family. It is believed that this dinosaur is related to the Diplodocus of North America and Mamenchisaurus of Asia. Therefore, several name changes of this genus took place and different types of family or clade have been suggested to this dinosaur.

In which geological period did the Cetiosauriscus roam the earth?

This species of dinosaurs roamed the Earth during the middle Jurassic period.

When did the Cetiosauriscus become extinct?

Cetiosauriscus became extinct more than 165 million years ago. Only a partial postcranial skeleton has been obtained, which is kept in the British Museum of Natural History, London.

Where did a Cetiosauriscus live?

The first fossil remains were found in Europe more than 100 years ago. Later in the year 1898, its postcranial skeleton partial remains were excavated from Peterborough, England by a group of clay workers. Sir Alfred Leeds handed over this dinosaur specimen to the British Museum of Natural History, London.

What was a Cetiosauriscus's habitat?

These dinosaurs of the Eusauropoda clade were herbivores and thus, they may have inhabited forests with dense vegetation and woodlands.

Who did a Cetiosauriscus live with?

The Cetiosauriscus might have lived solitarily or in herds to defend themselves from ferocious predators. They probably also lived in pairs during their mating season.

How long did a Cetiosauriscus live?

We do not know the exact lifespan of these dinosaurs due to a lack of information. However, we do know that the average lifespan of a dinosaur was about 20-30 years.

How did they reproduce?

Not much information is available on their reproductive behavior, owing to the partial skeleton remains retrieved. We do know that these whale lizard-like species of the Cetiosauriscus genus, reproduced by laying gigantic eggs. Just like other dinosaur-type species, for example, the Trinisaura and the Rebbachisaurus, the eggs of the Cetiosaurus, were amniotic, which provided all the essential nutrients to the developing embryo.  

Cetiosauriscus Fun Facts

What did a Cetiosauriscus look like?

These dinosaurs were thought to be about 49.2 ft (15 m) in body length with 7 t (6350.3 kg) body weight. Their name means whale-like lizard, owing to the presence of a whip-lash tail. The partial skeleton consisting of postcranial remains, which are kept in the British Museum of Natural History, London, highlights the fact that these whale lizards had much longer vertebrae than the Cetiosaurus genus of the middle Jurassic period. No skull remains were found and therefore, not much data is available on their entire body shape. Several species are attributed to this genus and this dinosaur of the Jurassic period has undergone name changes several times. More information is needed in order to get a full picture of these creatures. We do know that its tail was moderately long with scales on the back. Their forelimbs were as long as their hindlimbs. This suggests that they were fast runners.

The Cetiosauriscus had long vertebrae with a whiplash tail.

How many bones did a Cetiosauriscus have?

It's not known how many bones this dinosaur species had. The only partial skeleton obtained from England, which is kept in the British Museum of Natural History, London provides us information about the body length, weight, tail, and limb structure of these dinosaurs of the middle Jurassic period. However, we do know that the middle and posterior caudal region had 27 bones in this dinosaur.

How did they communicate?

Although not much data is available on their mode of communication, we do know that the Eusauropoda type species of the dinosaur used to communicate with their vocal and visual skills. They produced grunts and cracked calls.

How big was a Cetiosauriscus?

These dinosaurs of the middle Jurassic period were medium to large in length and were about 49.2 ft (15 m). They were 16.4 ft (5 m) tall and were way bigger than the Hypsilophodon, which were only about 6 ft (182.9 cm) in length and about 2 ft (61 cm) tall.

How fast could a Cetiosauriscus move?

The fossil of Cetiosauriscus stewarti kept in the British Museum of Natural History, London suggests that their forelimbs were as long as their hindlimbs. Further von Huene himself pointed out that they had long vertebrae. From these data, we can conclude that the whale lizard dinosaur was able to walk and run quite fast. However, more information is needed on their anatomy to assess the exact speed of these dinosaur species.

How much did a Cetiosauriscus weigh?

The fossil of the Cetiosauriscus kept in the British Museum of Natural History, London suggests that they weighed about 7 t (6350.3 kg).

What were the male and female names of the species?

No specific names are given to the male and female dinosaurs.

What would you call a baby Cetiosauriscus?

A baby Cetiosauriscus stewarti can be called a hatchling or a nestling as dinosaurs lay eggs.

What did they eat?

They were herbivores and their diet included various types of plants and branches. They used to roam about in forests and woodlands with lush green vegetation.

How aggressive were they?

Although not much data is available to assess their nature, it is safe to assume that they were not aggressive owing to the fact that their diet included plants exclusively. Further, the Cetiosauriscus period comprised several predators that imposed a massive threat to this species.

Did you know...

The taxonomy of Cetiosauriscus stewarti is of great significance due to its relationship with several dinosaur genera. In 1870, paleontologist Harry Govier Seeley named this species Ornithopsis hulkei and explained the relationship of Cetiosaurus taxonomy with them. The only difference between these two was the internal bone structure. Again in 1887, John Hulke named this species Ornithopsis leedsii based on the collection of pelvis, ribs, and vertebrae of the dinosaurs. This collection was brought about by an English farmer, Alfred Nicholson Leeds, who collected numerous fossil bones throughout his life from the Oxford clay. Later on, the famous English naturalist, Richard Lydekker, proved that the Ornithopsis and Cetiosaurus did not belong to the same taxon. Rather, the Ornithopsis included the Wealden fossils, whereas the Cetiosaurus included the Jurassic fossils.

What does Cetiosauriscus mean?

The word Cetiosauriscus means 'whale lizard-like'.

Is Cetiosauriscus a sauropod?

The Cetiosauriscus fossil has confused the paleontologists, which led them to debate a lot regarding their family or clade. At first, it was thought that these species might have originated from the Cetiosaurus clade. But as pointed out by von Huene himself, the Cetiosauriscus stewarti fossil had longer vertebrae. Their whiplash tail and herbivorous diet make them Sauropod dinosaurs.
