Adamantisaurus is a type of dinosaur fossil that was recovered from South America, in Brazil. Their clade was present for a long time during the Late Cretaceous epoch. Many dinosaurs that had features similar to Titanosaurs and lived in South America during the upper Cretaceous period were termed Adamatisaurus in the 21st century.

The name Adamantisaurus has a detailed history attached to its name. The genus was named after its actual feature in 1956. In 1956, the Adamantisaurus was published in print for the first time, but at that time the Brazilian animal did not have a name. It was not until 2006 that these species got a proper name of their own. They came to be known as Adamantisaurus. The description of these dinosaurs was given by two Brazilian paleontologists Reinaldo Bertini and Rodrigo Santucci in 2006. However, Sergio Mezzalira was a Brazilian geologist who gave a description of the features of the specimen and mentioned them first in a print. To know more about this dinosaur, keep on reading these amazing facts.

Adamantisaurus Interesting Facts

How do you pronounce 'Adamantisaurus '?

Adamantisaurus was a genus from the Late cretaceous and the name Adamantisaurus is pronounced like 'Ad-ah-man-te-nah-sore-us' in English.

What type of dinosaur was an Adamantisaurus?

The genus Adamantisaurus consisted of large and robust dinosaur species that resembled the dinosaurs of the Sauropoda clade. This dinosaur genus was classified as the Titanosaurian genus since they had long tail vertebrae and were found during the Late Cretaceous age. The titanosaurs belonged to the clade of the sauropods, therefore all the species of titanosaurs were Saurischian dinosaurs. They were the last of the Sauropoda clade, which makes them the last Saurischians to be present on earth under the subclass Dinosauria. The caudal vertebrae structure makes them a part of the Lithostrotia clade.

In which geological period did the Adamantisaurus roam the earth?

The Adamantisaurus was a Late Cretaceous genus of the Lithostrotia clade. The Adamantisaurus temporal range lasted from the middle of the Turonian stage up to the final Maastrichtian stage of the cretaceous. They existed on earth from 70-93 million years ago.

When did the Adamantisaurus become extinct?

The Adamantisaurus temporal range lasted for more than 10 million years on earth. Their existence dated back to somewhere in the middle of the Turonianian stage of the Late Cretaceous era. They became extinct well into the middle years of the Maastrichtian stage, or the latest stage of the cretaceous. It is believed that this clade of titanosaurs went missing around 70 million years ago from the earth.

Where did an Adamantisaurus live?

The Adamantisaurus fossils were discovered by Sergio Mezzalira in the Adamantina Formation of Brazil. Later they were described by Rodrigo Santucci and Reinaldo Bertini. The presence of their fossils in Brazil indicates that they originated in present South America.  

What was an Adamantisaurus's habitat?

The Adamantisaurus preferred to live in terrestrial habitats like forests, grasslands, as well as shorelines.

Who did an Adamantisaurus live with?

The fossils of large herbivore dinosaurs were often found in bonebeds, indicating that they lived in herds So the Adamantisaurus also might show herding behavior but there is no evidence of them living in herds.

How long did an Adamantisaurus live?

The Adamantisaurus lived for more than 10 million years on earth. The Adamantisaurus temporal range lasted from 70-93 million years ago, therefore they lived for 13 million years approximately.

How did they reproduce?

The Adamantisaurus reproduction was oviparous. They laid eggs and juveniles emerged from the eggs. There is no other information related to the reproduction process of the specimen.

Adamantisaurus Fun Facts

What did an adamantisaurus look like?

The Adamantisaurus was a genus of large dinosaurs of the titanosaur clade. They were characterized by a long neck and tail. There is no information about the anatomy of the dinosaur since only the fossils from its anterior part of the tail have been recovered.

Adamantisaurus was a herbivore dinosaur.

How many bones did an Adamantisaurus have?

The total number of bones present in the body of an Adamantisaurus is unknown. It is a poorly studied genus with only six caudal vertebrae that were found by the Brazilian geologist Sergio Mezzalira from the Adamantina Formation. The bones were described by the Brazilian paleontologists Rodrigo Santucci and Reinaldo Bertini later.

How did they communicate?

Dinosaurs used vocalizations to communicate with each other. They also had well-developed visualization which facilitated their communication.

How big was an Adamantisaurus?

Even though the Adamantisaurus was large in size it was believed to be a medium-sized titanosaur. Their size was roughly estimated to be around 43 ft (13 m) but currently, it is believed to be around 60 ft (18 m). They were bigger in size than the Janenschia.

How fast could an Adamantisaurus move?

The speed of the Adamantisaurus had not been determined but since they had a very large size, it is believed that they could move very slowly.

How much did an Adamantisaurus weigh?

The Adamantisaurus was a large animal with a long neck and tail. Previously, their weight was believed to be 5.5 ton (5000 kg) but later it was estimated from the Adamantisaurus skeleton weighed 15.4 ton (14000 kg) approximately.

What were the male and female names of the species?

The male and female species do not have any specific names. Both of them were known as Adamantisaurus.

What would you call a baby adamantisaurus?

A baby dinosaur is referred to as a nestling or hatchling.

What did they eat?

The Adamantisaurus was a herbivore dinosaur genus, they fed on plant matters. The diet of the species presumably included plants, leaves, grass, and shrubs.

How aggressive were they?

Although the estimated height and length of the Adamantisaurus can appear dangerous to us, they were not very aggressive. It was an herbivore species so it did not attack any prey aggressively like other flesh-eaters.

Did you know...

Even though there is a limited description of Adamantisaurus, similarities have been observed with some other titanosaurs like Aeolosaurus and Trigonosaurus as well as with some other sauropods that were recovered from the Adamantina Formation.

What does Adamantisaurus mean?

The name Adamantisaurus is derived from the place from where its fossil material was discovered. They described the Adamantisaurus fossil much later from when it was discovered by the Brazilian paleontologist Sergio Mezzalira from the Adamantina Formation located near Brazil. The Greek word sauros is incorporated in the term Adamantisaurus. The Greek word sauros means lizard and it is the most common suffix that is used to describe a dinosaur. Combining the two words called Adamatina and sauros respectively, the genus name Adamantisaurus translates to Adamantina lizard‭. The holotype of only one proven specimen of the Adamantisaurus has been discovered from the Adamantina Formation of Brazil. The specific name of the type species, Adamantisaurus mezzalirai was named in honor of the person who discovered its fossil material.

Is Adamantisaurus a sauropod?

Sauropoda is a clade of the Dinosauria subclass, which includes several herbivorous dinosaurs, that have typical characteristic features like a long tail and an extremely long neck with multiple vertebrae. They also had a smaller head in comparison to the rest of the body. A large animal showing such typical features was classified as a sauropod based on what was inferred from its remains. Several extinct genera of lizard-hipped saurischians have been classified under the clade Sauropoda. Even though the sauropods appeared during the Late Triassic period, they became widespread during the upper Jurassic period. The Late Cretaceous sauropod evolved from the early sauropod of the Late Triassic.

The Titanosaurs were a group of large dinosaurs that belonged to the clade Sauropoda. Titanosaurian dinosaurs were characterized by long vertebrae, the largest land animal ever recorded on earth was believed to be a titanosaurian sauropod. The holotype of the genus Adamantisaurus recovered from the Adamantina Formation of Brazil was an upper Cretaceous species. Only the caudal vertebrae of this clade of dinosaurs were found. The six tail long caudal vertebrae suggest that it was a large animal that belonged to the Titanosaurian clade. As titanosaurs, they naturally fell under the classification of the sauropod dinosaur. It can be assumed from the remains that it was a large animal with a long neck and tail that roamed around South America.
