The middle-age Jurrasic period was a complex period as the fossils recovered from this period are extremely limited, particularly the fossils of the animals that prevailed on land like dinosaurs. However, certain places in England, China, Russia, Scotland, and Madagascar contain most of these fossils.

This age is further divided into different stages, such as the Bathonian age and the Cardidons belonging to this age.

From the remains, it has been deduced that Cardiodons were a type of herbivores Sauropoda from England. Initially, the Cardiodons were placed under Cetiosauridae.

but recent studies have suggested that they are Turiasaurus, which happens to be one of the largest dinosaurs that can be found in Europe. Cardiodon is probably the first-ever sauropod genus that was named and the credit goes to Richard Owen.

Nevertheless, at the time of naming the dinosaur, Richard Owen was not familiar with the nature of Sauropods. The only part that was discovered was a tooth.

Therefore, Cardiodon is also referred to as 'heart tooth' as the shape of the tooth resembled a heart. They are considered gigantic dinosaurs, but due to a lack of data it is not completely evidenced.

This species was discarded from Cetiosauridae and was placed under a new genus Cardiodon by Richard Lydekker. And Cardiodon rugulosus is the only type species under this genus.

Cardiodon that is not linked to Turiasaurus was named by Richard Owen in 1841. The 'cardiodon' means 'heart tooth' and it is pronounced as 'CAR-dee-oh-don'.

What type of dinosaur was a Cardiodon?

According to the description given Cardidions are contemplated as enormous herbivorous dinosaurs. It was obscure to place it under Cetiosauridae but now it has been removed by Richard Lydekker to Cardiodon in 1890.

In which geological period did the Cardiodon roam the Earth?

Cardiodons belonged to the late Bathonian age which is evident from the specimen of the tooth. The duration of the is age is from 168.3-166.1 Ma.

When did the Cardiodon become extinct?

The accurate explanation behind the extinction of this species is not mentioned. However, it is assumed that they lived on Earth approximately 170 million years ago.

Where did Cardiodon live?

The subject has been excavated from England precisely in the geological formation of Forest Marble that is situated in Wiltshire of England.

What was the Cardiodons' habitat?

Cardiodons were plant-eating dinosaurs therefore they must have lived in the terrestrial region where plants were in abundance.

Who did the Cardiodon live with?

Sauropods mostly had different social configurations. Some of them would stick to groups while others would live solitary. And, whether this specific Sauropod species lived in group or solitary is not mentioned.

The average life span of Cardiodon is not stated.

How did they reproduce?

The exact method of reproduction of the Cadiodon is not illustrated. Regardless, they reproduced sexually and produced eggs. But, their gestation period or clutch size is not available.

Cardiodon Fun Facts

What did the Cardiodon look like?

There are insufficient data available about the Cardiodons. These dinosaurs were massive but their size and weight are not determined. The tooth crown region is broad and short, unlike the Apatosaurus which had chiseled teeth.

Furthermore, the crown is curved as well towards the inside. The outer portion is prominently curved convexly from the front till the back. And, a shallow groove runs parallelly till the posterior edge.

The tip of the crown is tapered slightly. Besides, these characteristics denticles are also absent. It is not clear whether they had neck frills.

On the basis of research it is determined that Cardidions were quadrupedal which means that walked on four feet.

The precise nature or temperament of Cardiodon can be hard to describe with any proper information. But Sauropod herbivore dinosaurs were docile and not very aggressive.

Did You Know…

The name of the Cardidon is a combination of two Greek phrases. The meaning of 'Kardia' is 'heart' while the meaning of 'don' is a 'tooth' thus its name.

In 1884 the Latin phrase 'rugulosus' was added which implies 'wrinkled'.
