If you are fascinated by the giant reptiles that roamed on our planet in the prehistoric age, then you are in for a treat. We present to you the Sarmientosaurus.

This is a relatively new species of titanosaur that have been discovered off late. The Sarmientosaurus had an approximate height of around 39 ft (12 m) and weighed around 10 t (10000). They had a characteristic long neck and a large head. In comparison to their body, the neck and the tail were the longest parts of their body. The skull had huge eye sockets, which proves that these dinosaurs had large eyes. These were herbivorous dinosaurs that existed almost 95 million years ago in the Turonian age. The remains of this dinosaur have been excavated in modern day Argentina. It is assumed that this titanosaur lived in Argentina and South Africa. These were herbivorous animals that fed on plants. Fossilized teeth remains have also been found. It is estimated that these dinosaurs had around 28-29 teeth.

Sarmientosaurus Interesting Facts

How do you pronounce 'Sarmientosaurus'?

The ideal way to pronounce Sarmientosaurus is 'Sir-me-n-tho-sau-rus'.

What type of dinosaur was a Sarmientosaurus?

The Sarmientosaurus (Sarmientosaurus musacchioi) was a type of sauropod dinosaur that belonged to the diverse group of dinosaurs Titanosauria.

In which geological period did the Sarmientosaurus roam the earth?

It has been estimated by scientists and geologists that the Sarmientosaurus was said to roam on our planet during the upper cretaceous period. The upper cretaceous period was a part of the late cretaceous period and that existed almost 95 million years ago during the Turonian age.

When did the Sarmientosaurus become extinct?

Owing to very limited information being available, the time period in which the Sarmientosaurus became extinct is not accurately known. However, we can make a rough estimation of the period in which they lived and the period in which they became extinct. In the majority of the cases, each type of dinosaur roughly lived for almost 10 million years on earth. Since the Sarmientosaurus lived during the late cretaceous period, it can be assumed that they might have gone extinct during the Santonian age of the late cretaceous period.

Where did a Sarmientosaurus live?

The recent discovery of the Sarmientosaurus skull and other crania portions in Argentina has led scientists to believe that these species of sauropod dinosaur lived in modern day Argentina and South Africa.

What was a Sarmientosaurus' habitat?

During the Cretaceous period, the landforms of the seven continents were much closer to one another as the separation of the continents from one another was still ongoing. During this period of time, the sea level was much higher which led to the formation of numerous inland islands and landmasses. Due to persistent volcanic activity during that time frame, the general temperature and the humidity of the earth were much greater. This was beneficial in facilitating the growth of bushes, shrubs, and trees. Thus we can say that the Sarmientosaurus lived in a wide range of habitats like grasslands and forests.

Who did a Sarmientosaurus live with?

Since the Sarmientosaurus is a very recently discovered species of titanosaur, (discovered in 2016) not much is known about this new titanosaur. However, we can make an assumption based on the type of dinosaurs they were. The Sarmientosaurus were primarily titanosaurs that were a part of the sauropod. Since the sauropod was a highly social animal they lived in groups or herds and traveled together (as evident from their fossil remains), we can assume that the Sarmientosaurus were also social animals and could have lived in herds.

How long did a Sarmientosaurus live?

Unfortunately owing to very less information being available, the exact duration of the lifespan of the Sarmientosaurus (Sarmientosaurus musacchioi) is currently undetermined as well as unknown. The entire species of Sarmientosaurus is supposed to have existed for almost 10 million years while the exact lifespan of each individual is not known. However, we can make an assumption based on the lifespan of sauropods and titanosaurs. Sauropods had quite a large lifespan. Few giant sauropods survived for almost 300 years while the smaller ones had an average lifespan of around 70-80 years. Thus we can assume that the probable lifespan of the Sarmientosaurus was likely to be around 30-50 years.

How did they reproduce?

Owing to very little research material being available, not much is known about the reproductive process of the Sarmientosaurus. But we can compare it to the likes of dinosaurs in general. Dinosaurs were egg laying reptiles. The freshly hatched young ones were tiny in size but they grew to their gigantic heights in a small amount of time.

Sarmientosaurus Fun Facts

What did a Sarmientosaurus look like?

Sarmientosaurus musacchioi had very special skulls. When the complete skull was discovered it was found out that almost 40 percent of the Sarmientosaurus skull consisted of the eye socket. These dinosaurs had huge eyes, which greatly increased their eyesight. They had long necks extending from the base of their body. The tails were also large in proportion to their body.

How many bones did a Sarmientosaurus have?

The Sarmientosaurus (Sarmientosaurus musacchioi) is a very recently discovered new species of dinosaurs, so a very limited set of information is available on them. Moreover, apart from the complete skull and a few bones of the neck, the entire skeleton of this species of titanosaurs has not been found yet and thus it would be almost impossible to know how many bones these species of sauropods had.

How did they communicate?

It is impossible to know how dinosaurs communicated with one another. However, scientists have conducted numerous research and have come to the conclusion that these gigantic beasts used calls and signs to effectively communicate with one another. Hoots and cracking and cracking sounds could have been the main means of vocal communication among these big lizards. Just like all other reptiles of the modern age, dance and body signs were supposedly prevalent for the dinosaurs too.

How big was a Sarmientosaurus?

Sarmientosaurus musacchioi had a length of around 39 ft (12 m). When compared to other dinosaurs like Tapuiasaurus and Nemegtosaurus, Sarmientosaurus musacchioi was way bigger than a Tapuiasaurus and almost the same size as a Nemegtosaurus.

How fast could a Sarmientosaurus move?

The exact speed at which the Sarmientosaurus (Sarmientosaurus musacchioi) moved is currently unknown and undetermined. However, it is estimated that a sauropod could easily move at speeds of 4.5 mph (7.2 kph).

How much did a Sarmientosaurus weigh?

The Sarmientosaurus had a weight of around 10 T (10000 kg).

What were the male and female names of the species?

There are no distinct names that have been assorted to male and female dinosaurs. They are just known as males and females.

What would you call a baby Sarmientosaurus?

Just like most reptiles, a baby dinosaur is known as a hatchling. Therefore in the case of a baby Sarmientosaurus, it would also be known as a hatchling, or more appropriately a baby Sarmientosaurus hatchling.

What did they eat?

The Sarmientosaurus were herbivores, animals that only feed on plant matter. Titanosaurs like these all belonged to the sauropods were all herbivores. Their gigantic size and long necks made it extremely easy for them to eat trees, bushes, and shrubs. For the Sarmientosaurs, it was extremely beneficial. As these dinosaurs had large eye sockets, meaning they had gigantic eyes in comparison to other dinosaurs, it became extremely easy for them to spot plants, bushes, and shrubs and their elongated long necks made it even easier for these dinosaurs to reach bottom growing plants.

How aggressive were they?

It is unknown whether these dinosaurs were aggressive or not. However, evidence suggests that these dinosaurs were not aggressive to other dinosaurs or other animals. Their gigantic sizes made these titanosaurs immune to predation. And thus they didn't find the need to protect themselves from other dinosaurs.

Did you know...

The Sarmientosaurs, aka Sarmientosaurus musacchioi have been named after the late scientist and biologist Eduardo Musacchio.

What fossils and bones of the Sarmientosaurus have been found?

Though not the entire skeleton has been discovered, however, significant portions of the body and bones have been excavated as fossils by scientists. An almost complete skull with significant parts of the neck has been found. Seven vertebrae have been excavated carefully along with different parts of the jaws that have been found of the Sarmientosaurus.

What species of Sarmientosaurus are there?

As of today, only one species, the Sarmientosaurus musacchioi has been discovered.
