A big dinosaur


Name: Aepisaurus

Diet: Herbivore

Weight: 12 tons

Period: Cretaceous

Found In: Europe

The majesty, design and imposing nature of the amazing Aepisaurus has long captivated the hearts of lovers of the subject, positioning it as one of the best known in the world today.

What does the name Aepisaurus mean?

This name means “High Lizard” and comes from the Greek υψηλή (Aepi) which is understood as high and σαύρα (saurus) which is understood as lizard.

History of the discovery

The current representations of this animal based on its fossil record are quite complete, thanks to this we have a clearer idea of the time in which it lived as well as its culinary taste and size.

The genus Aepisaurus was first named after Paul Gervais.

This illustrious paleontologist described the name of this genus based on the humerus of this animal, the bone was exactly 90cm long and its width was 33cm.

Later there were findings that found a cone-shaped tooth that could belong to a species of the family Aepisaurus, but for its size is believed to be a much larger species.

At the present time it is quite doubtful the date in which the fossil discovery of the Aepisaurus was made.

This is because the literature that has information on the subject has misspelled several times the year of the discovery, and the oldest data date back to 1825.

However, to say that it was in this year that the discovery was made would not be prudent.

The data on the discovery of this dinosaur is accurate especially in the region where it was made.


The first fossil was found in the region of Mont Ventoux very close to Bédoin, a French town in the western district of Carpentras.

Its records

Among its fossil records, there is information that particularly dates from an Aepisaurus bone.

Practically the most relevant information about its size and other specifications can be found in this one; thanks to this surprising finding, today we have ample information regarding the figure of this animal.

When did it live?

In the middle of the Cretaceous period, we find the results of the analysis made on the fossil of the famous sauropod known as Aepisaurus.

Thanks to this analysis we have more information about its stay on earth.

It is assumed that the Aepisaurus lizard lived in the mid-Cretaceous period, precisely 100 million years ago in the Albiense, which is Europe today.

It should be clarified that the Albiense is the sixth division in the Cretaceous period and the last one in this period, which expands from 113.1 to 100 million years approximately.

Aepisaurus Characteristics

Although their design varies from one specimen to another, there is a similarity between the fossil records and the detailed analysis performed on their femur.

It is assumed that this animal reached a height of approximately 4 meters and a length of 20 meters. It is believed that this herbivore could weigh between 11 and 12 tons.

The average-sized sauropod known as Aepisaurus had a dent in its head, perhaps in order to allow it to put this almost whole head in the water without drowning.

This animal was probably covered with plates of bone to protect it from its natural predators.


The design of this animal, as well as the complete picture of its physiognomy, is circulated in many books and films that specify its colour, size and dynamics.

However, these assumptions are largely based on the fossils we have so far.

Thanks to the advances in technology, it is possible to have a more complete picture of the characteristics of this animal.

This fact has made it possible to give life to hundreds of designs that are kept in museums, natural parks and amusement centers that undoubtedly show the wonderful nature of the Aepisaurus.
