They were 100 ft (30.5 m) long and 45-55 tons (40823.3-49895.2 kg) in weight. They had a number of huge bones in their body. The right humerus that was found was nearly 69.2 in (1.8 m) long. They had a long neck, long tail, small head, and a huge body.

They had strong shaft legs for carrying their huge body. Their skeletal and neural systems were finely built. Notocolossus' were in the dinosaur clade Sauropoda, Macronaria, Saurischia and Sauropodomorpha.

This was just a small introduction. For detailed information about this dinosaur, continue reading this whole article. You will be amazed!

Notocolossus Interesting Facts

How do you pronounce 'Notocolossus'?

The Notocolossus was a huge dinosaur species that roamed the continent of South America. They were a giant sauropod dinosaur species in the genus Titanosauria.

From their fossils, it is known that they were herbivorous animals. Their specimens were found in the Mendoza province in Argentina. The name Notocolossus seems tricky but can be easily pronounced as 'noto colos sus'.

What type of dinosaur was a Notocolossus?

The Notocolossus gonzalezparejasi were giant titanosaurs that inhabited the Earth during the Late Cretaceous period. It was a herbivorous and gigantic new dinosaur from Argentina.

They belonged to the dinosaur clade Saurischia, Sauropodomorpha, Sauropoda, Macronaria and Titanosauria. Scientific reports on the Notocolossus specimens tell us that they were in the family Titanosauridae. Their genus name is Notocolossus and their scientific name is Notocolossus gonzalezparejasi.

In which geological period did the Notocolossus roam the Earth?

Notocolossus gonzalezparejasi roamed the Earth during the late cretaceous period. They were present in the Plottier formation in Mendoza, Argentina. According to vertebrate paleontology, the Notocolossus were a species of gigantic new dinosaur from Argentina. They were plant-eaters and required a lot of food for maintaining their size.

When did the Notocolossus become extinct?

Notocolossus dinosaurs were present on Earth during the later Cretaceous period. They were giant titanosaurs that inhabited the continent of South America. It is not exactly known when they went extinct but it is vaguely assumed that they went extinct during the end of the Cretaceous period. According to the Notocolossus fossil, they were a new titanosaur species.

Where did a Notocolossus live?

The Notocolossus was a terrestrial dinosaur. According to the studies on this Dinosauria species, it is clarified that they were huge plant-eaters that inhabited the Mendoza province.

What was a Notocolossus' habitat?

Notocolossus were inhabitants of the Plottier formation. The specimen remains of these Sauropoda dinosaurs had been excavated from the Mendoza province in Argentina. It is assumed that these giant titanosaurs lived and roamed around the continent of South America.

Who did a Notocolossus live with?

There is no exact record of the Notocolossus being either social or solitary. We assume that they were social dinosaurs. New sauropod dinosaurs, like the Notocolossus, were herbivorous in nature and it is commonly seen that herbivorous species live in groups in order to ensure protection against hunters and predators.

How long did a Notocolossus live?

There is no information available on exactly how long a Notocolossus lived for. They were a giant titanosaur species that lived on Earth during the later Cretaceous period. They were sauropods who were present on Earth for several million years. They were big in size and can readily be compared to the Argentinosaurus and Brachiosaurus.

How did they reproduce?

If we go back to their natural history, the Notocolossus were in the genus of titanosaurs that lived in Argentina. They were humungous reptiles that lived on land.

We know that reptiles lay eggs when giving birth to their babies and it is believed that Notocolossus dinosaurs must have had done the same. They also would have had a breeding season when their species would have mated.

A lot of things surrounding dinosaurs are purely based on imagination and how they would have reproduced is one of those.

Notocolossus Fun Facts

What did a Notocolossus look like?

The Notocolossus is a sauropod dinosaur species that lived in Argentina. If we consider their natural history, we shall see that they were in the genus of titanosaurs and were herbivorous in nature, and ate plants.

They were present during the later Cretaceous period. Their specimen remains were found in Mendoza. The holotype skeleton was found in the Plottier formation.

All the specimens found were not complete and this is why a lot of integral information about them is not available. According to the fossils, they were massive sauropods. Sauropod dinosaurs had a long tail, a really long neck, a small skull, and a body of huge width.

They also had four broad and strong legs and well-built leg bones. The femur and other leg bones were strong and well built.

The tarsal, metatarsal, and phalanges in their feet were comparatively smaller. They had a few claws in their feet and the vertebrae were really long because it started from the skull and went to the tip of their tail.

All titanosaur species had a small skull. Their skull was narrow-sized and had a deep snout. The specimens of Notocolossus dinosaurs found were not complete and this why complete information on their body is not available.

However, Notocolossus dinosaurs were considered to be one of the biggest titanosaurs that ever existed. Clearly we can think of their huge mass.

The upper arm bone, the humerus, was alone 69.2 in (1.8 m) long. Due to the incomplete fossil, the exact size and weight of Notocolossus dinosaurs are not known, but we can assume that they were in huge in size with a weight range of several tons.

The length of Notocolossus is assumed around 100 ft (30.5 m) with an average weight around 45-55 tons (40823.3-49895.2 kg). From this, we can easily estimate the Notocolossus size and mass.

Notocolossus were one of the biggest dinosaurs in natural history

How many bones did a Notocolossus have?

While excavating the Notocolossus fossil, it was incomplete. The exact number of bones present in the Notocolossus body is still not known. However, they had a long vertebra, a small skull, strong femur and humerus, and small feet bones namely tarsals, metatarsals and phalanges.

How did they communicate?

How big was a Notocolossus?

Notocolossus' were big dinosaurs that lived in Argentina. They were one of the biggest titanosaur species that lived during the later Cretaceous period. Their holotype specimens were found in the Plottier formation. They had a body length of around 100 ft (30.5 m) and weight of around 45-55 tons (40823.3-49895.2 kg).

How fast could a Notocolossus move?

Notocolossus' were huge dinosaurs in the Titanosaurs genus. Due to their huge body and enormous weight, they were slow in speed.

How much did a Notocolossus weigh?

Studying the holotype specimens, it was found that these dinosaurs were huge herbivores. There is no record of their size and weight but can be assumed that their length was around 100 ft (30.5 m) and weighed around 45-55 tons (40823.3-49895.2 kg).

What would you call a baby Notocolossus?

Like all other baby dinosaurs, a baby Notocolossus is also known as a hatchling.

Probably not, they were huge dinosaurs that mostly had a calm temper.
