Barapasaurus (/b@,ra:p@’so:r@s/ b@-RAH/) is one of the geniuses belonging to the basal sauropod dinosaurs found in Early Jurassic rocks of India. The only species that is known is B. tagorei. Barapasaurus is found in the lower portion of the Kota Formation which is dated back to early Sinemurian and Pliensbachian stage that formed the first part of Jurassic. This makes it one of the first known sauropods. Barapasaurus is identified from around 300 bones that belong to more than six people which means that the skeleton is almost entirely known, apart from the anterior cervical vertebrae as well as the skull. This means that Barapasaurus among the most well-known sauropods dating from the beginning of Jurassic.
Its name Barapasaurus (“big-legged Lizard with big legs”) originates from bara meaning “big” and pa which means ‘leg’ in many Indian languages, including Bengali as well as Bengali. Greek word sauros is a reference to lizard’. The name was adopted in the form of a nominum because the femur that measured over 1.7 meters was discovered in 1961. The exact name tagorei refers to ‘Tagore’s’ that honors Bengali poet writer, painter, writer as well as musician Rabindranath Tagore. In the beginning, fieldwork conducted in the year 100 years of Tagore’s birth.
While it was a relatively young and primitive sauropod Barapasaurus displays the plan of construction common to latersauropods that are more closely related The cervical vertebrae were extended, which resulted in an extended neck. The trunk was small and held columnar limbs that suggest an obligate quadrupedal position. The size of the animal, which is estimated to be around 12-14 meters in length and 7 tonnes in weight is similar to that of earlier sauropods.
The vertebral column has several traits that are typical of later sauropods that enabled them to achieve huge body size, however in the later sauropods, these traits are more advanced. The neural and central spines display early indications of hollowing to save weight as a measure. Dorsal vertebrae can be stabilized by articulations of the hyposphene-hypantrum, as well as extensions that connect the vertebrae. Sacrum strength is increased with another 4th sacral vertebra.
In the skull only three complete tooth and 3 crowns are recognized. The longest known tooth measures 5.8 centimeters tall. Similar to the later sauropods The teeth have spoon-shaped teeth and exhibit wrinkled enamel. The most important characteristic is the serration that is coarse.
The fossils are all known to be from one location within the area of the village of Pochampally, Pin code 442504, that borders Telangana state (Pochampally Sironcha Taluka, Gadchiroli District, Vidarbha, Maharastra located situated in Central India. India). First bones were found in the year 1958, however the majority of bones were discovered between 1959 and 1960. By 1975, these findings were scientifically described in the paleontologist Sohan Jain and his colleagues. Then, in 2010, an even more thorough osteological description was released by Bandyopadhyay and coworkers. The bones are stored within the collection for paleontology at the Indian Statistical Institute (ISI) The majority of the bones form part of a mounted collection in the Geological Museum of the ISI.
