17 Roar-some Rajasaurus Facts That Kids Will Love

Read about Rajasaurus facts to learn about these horned dinosaurs from the Lameta Formation, India.

The Rajasaurus was a carnivorous abelisaur theropod dinosaur and was known as 'king' or the 'king of lizards'. The dinosaur was discovered in the Narmada River valley near the Rahioli region of the Kheda district of Gujarat, India. The discovery of this dinosaur dates back to the early years of 1982-1984 when the Indian scientist Suresh Srivastava discovered the bones and fossil remains. This abelisaurid carnivore dinosaur was declared anew dinosaur on 13 August 2003.

The name Rajasaurus narmadensis means 'princely lizard of the valley of Narmada'. These dinosaurs from the Late Cretaceous period had an unusual head crest and were closely related to the Majungasaurus from Madagascar, Africa, and the South American Abelisaurus. According to the description and characteristics of Rajasaurus, these abelisaur theropods were massive and huge in size.

For the discovery of the Rajasaurus, from handling their data, content, and research, everything is being credited to the paleontologists Paul Sereno of the University of Chicago from America, and Suresh Srivastava from India. The name Rajasaurus was given by Jeff Wilson from the University of Michigan in 2003. They both created the Indian dinosaur Rajasaurus skeleton display. The fossil remains mainly have a partial skeleton and a skull. Apart from the Kheda district, fossil bones have also been discovered in the range of Jabalpur in Madhya Pradesh.

The Rajasaurus became extinct at the end of the Late Cretaceous period when most dinosaurs were believed to go extinct.

Where did the Rajasaurus live?

The Indian abelisaur Rajasaurus lived in the Narmada River valley region of the Kheda district in Gujarat and the upper region of Narmada in Jabalpur, Madhya Pradesh. The closely related relatives of these theropods were believed to be from Madagascar, Africa, and South America. The Rajasaurus was discovered in the Lameta Formation of India.

What was the Rajasaurus's habitat?

These Indian theropods, the Rajasaurus, lived near the Narmada River range of India, where the temperature is believed to have been tropical and humid. From the history of Rajasaurus, it was believed that these dinosaurs were tropical-level carnivores that lived by the side of river valleys and woodlands. 

Who did the Rajasaurus live with?

There is not much research is done and not enough data and content available to determine whether these species lived in solitude or in groups. As they were large carnivore theropods, they must have lived in solitude and the females might have lived only in groups of two or three consisting of their hatchlings, but there is no strong evidence available in this regard. Only general assumptions have been given by scientists.

How long did a Rajasaurus live?

The Rajasaurus lived in the Late Cretaceous period, from 70 million years ago to 65 million years ago. There is no data available or research done in regard to the length of their life expectancy.

These hard-crest skull abelisaurid theropods with long length and huge massive size could have reproduced by mating and laying eggs in clutches. Not much data and content is available in regard to their reproduction.

Rajasaurus Fun Facts

What did the Rajasaurus look like?

The description, featuresm and characteristics of these theropods from India are like any other large abelisaurid. From their specimen history and evaluation, they were closely related to the Madagascar Majungasaurus and South American Abelisaurus. The bone fossils and remains consisted of a partial skeleton with a head crest and skull. A Lametasaurus specimen had been lost, otherwise, the Rajasaurus and Lametasaurus had a close link between this feature. The skull was partial and only a few pieces of the jaws and braincase were found. A few other parts consist of hip bones and hind legs with a long hardtail and vertebrae bones remains. They were believed to have a low, rounded horn growing from the nasal bones of their skull, which was similar in features to the Madagascar Majungasaurus horn. The horn would have been around 1.6 in (4 cm) thick on the nasal and head bones. They had a special feature in their olfactory tract which helped them to smell the things around them.

The Rajasaurus had a strange head crest rarely found in carnivores.

How many bones did a Rajasaurus have?

The exact number of bones in these theropods from India has not been evaluated and is unknown. Only a partial skeleton and skull have been found with jawbones, hip bones, and spines of the tail. They also had a very unusual head crest.

How did they communicate?

There is not much about their communication, but as they had an olfactory tract, they could have communicated using chemical smells and tactile cues.

How big were the Rajasaurus?

The royal or princely lizard, Rajasaurus, was 25-30 ft (7.6-9 m) long in length and 8 ft (2.4 m) tall. They were smaller than a T. rex.

How fast could a Rajasaurus move?

The exact speed of these dinosaurs is not evaluated and is unknown, but as the dinosaur was compared to the Tyrannosaurus rex and Majungasaurus, they could have been fast in their locomotion like them. 

How much did a Rajasaurus weigh?

According to the description, the Rajasaurus weighed 3-4 tons (2721.5-3628.7 kg).

What were the male and female names of the species?

Male and female dinosaurs of this species did not have any specific names and were known by their common names.

What would you call a baby Rajasaurus?

The babies of Rajasaurus dinosaurs were called hatchlings and juveniles.

What did they eat?

The Rajasaurus was a large theropod carnivore and must have hunted and fed on small animals, mammals, and other small dinosaurs such as Mahaan and Baahu. They had strong jaws and teeth.

How aggressive were they?

These dinosaurs were aggressive, which is evident on the basis of their food habits and comparison with the world's strongest dinosaurs such as the Tyrannosaur rex or T. rex. The jawbones were strong and their bite might have torn the flesh into pieces. As they themselves were ambush predators, they could have been very competitive and might have had predators like the Indosaurus.

Did you know...

Rajasaurus vs T. rex: The Rajasaurus was a carnivorous abelisaur theropod dinosaur and was known as the 'king' or 'king of lizards' from India, while the T. Rex was a bipedal carnivore theropod from North America. The T. rex and Rajasaurus both lived during the Maastrichtian period but lived in different regions. If they got into an altercation, the Rajasaurus would flee because the T. rex had a huge size, which might have ended without a fight.

Dinosaurs lived in the Mesozoic era.

Why are they called Rajasaurus'?

They are called Rajasaurus because of their large size. They were ferocious and carnivores, making them stronger. The word 'Raja' means 'king', and they were called the 'royal' or 'princely lizards'. 

Is the Rajasaurus stronger than the T Rex?

Yes, scientists claim that the Rajasaurus was stronger than the T. rex on the basis of their jaws and teeth. The Rajasaurus was believed to have a stronger bite in comparison to the T. rex, but if you look at the overall aspect, then, of course, the T. rex would have been stronger due to their huge size and robust built body.
