Rajasaurus:The Indian Dinosaur

Rajasaurus

 Rajasaurus (Raja ', which means "king" (derived from Sanskrit, "king of lizards") is a species of carnivore abelisaurian theropid dinosaur with an unusual head crest. Between 1982 and 1984, Suresh Shrivastav of Indian Geological Survey (GSI) had discovered fossil bone. Digging from the river Narmada in Raholi in the Mahasagar district of Gujarat, discovered on August 13, 2003, American and Indian sciences By duties went declared as a new species of dinosaur

The University of Chicago's Paleolanist Paul Sereno, Jeff Wilson of the University of Michigan, and Srivastava worked together as an Indo-American group to study the fossils of the Narmada River. Fossils represented partial skeletons of new species of Rajasaurus Narmadensis, which means "the kingdom from Narmada valley lizard." Bones of fossil fossils of Rajsauras have also been found in the upper area of ​​Narmada in Jabalpur in the state of Madhya Pradesh.

Rajsaurus was an Abiliceroid, a member of a group of tropical hunters, who lived only on the lands, which were part of the Gondwana, like the most populated country like Africa, India, Madagascar and South America. Rajasaurus meets Madagascar from a contemporary oblique near Majugasaurus, an island which was separated from the Indian landland approximately 20 million years ago. This was found in the form of a abelisaurid through a phylogenetic analysis of structural characteristics, and its nasal bone was described as a carnotaurine abelisaurid (cabinotransis including suburban) due to its occupation of the configuration and development ("excrescence") frontal Rajasauras on bone form a single nose-frontal horn with its other breeds, its propratemporal fenestrae (long holes in the upper rear of the scalp), and the form of Iliya (hip theory of bones) Land, which offers a transverse ridge. Separate the Brevis shelf from the hip joint.

Rajasauras was identified with partial skeleton which included part of the scalp (brain case), spinal cord, hip bone, hind legs and parts of the tail. This sample, GSI 21141 / 1-33 genes and species type acts as sample. In 2010, Gregory S. Paul estimated its body length in eleven meters, its weight was four tons. In 2016, its length was approximately 6.6 meters (21.7 feet), which was in wide-ranging analysis of the size of the Abellisur. Preserved by the scalp, it shows that it was a specific low round horn, made up of the result from the bones of the nose and frontal.

Narmada river in central India, after the journey of 1,512 km (815.2 miles) in a valley valley and finally in the Arabian Sea, its valley originates from the eastern drains of the west. Since the late 19th century, information about dinosaur bones has been reported from the Narmada Valley, some of which are related to titansaurus indusus.

The history of fossils called Rajasaurus begins in 1981. When GN Dwivedi and DM Mohawi were on the geological, mapping mission of the Geological Survey of India, the workers of ACC cement in Raholi in Gujarat showed them like a smooth ball, limestone structures from the mine became these "balls" dinosaurian eggs geologists Also found that fossil-egg limestone bed is a layer of thick sandstone and abundant dyes Nasserian fossils were mixed with bones.

During the years of 1982-84, GSI geologist Suresh Shrivastav of Paleontology division of Western Region of GSI gathered a large number of bone fossil pieces from Riceoli, and also mapped the area properly. These fossils were taken to Palaeontology Division in Jaipur to identify. Under the supervision of SC Pant, UB Mathur and Suresh Srivastava gave birth to the publication of many research to clean many skeletal parts (brain, dorsal and convex vertebrae, secretion, thigh bone, upper arm, shin bones and others). Papers In 1994-9, a special deterioration in excessive activity till the MoU signed with the University of Punjab was signed.

In 2001, American scientists continued research on fossils sponsored by the American Science Institute, New Delhi and the National Geographic Society, United States, America, Paul Sereno and Jeff Wilson began the reconstruction of the collections in 1983 and 1984. Dinosaur bones are gathered in Following a detailed study of maps prepared by Shrivastav, the team of scientists was able to rebuild partial skulls, left and right hip bones and a serum. They understood a part of a skull and a horn as the dinosaurs found in Madagascar. Fossils of Rajsauras were also found near Jabalpur in Madhya Pradesh. In all, the collected fossils include partial scalp, limb bones, hip bones, and vertebrae.

Although 2003 was formally described in Rajasaurus, the fossils described in 1923 could be related to this species. Charles Alfred Mattel has described lemateosaurus inguors in that year, in which there are samples, including ileums found in Bal Simla, a sarum, shin bone, and shield cloth. Later Lametasaurus was shown as a fantasy, and Wilson et al suggested that Elim and Serram (now lost) were examples of similar famous monarchs.

There may be additional information about the development relations of abelisaurs from the discovery of the Rajasaurus, because there were mainly different bones in India's previously mentioned specimens. At a press conference in 2003 on the discovery of RajaSaurus, Serrano said:

The research that will be done to search the world before, it was important because it will help in connecting the current knowledge of dinosaur related to the family of the Abilisor predators and adding a new angle to the dinosaur in the Indian subcontinent.
