Bruhathkayosaurus is a massive sauropod dinosaur; with holding the candidate for being the most massive/largest dinosaur ever to exist; from the early Maastrichtian, Late Cretaceous of India. It was one of the largest animals known, and the largest dinosaur found to date, with a length of 33 to 44.1 meters and a size of up to 110-170 tons.

Discovery[]

Only the hip and a few leg bones have ever been discovered. Its remains were found in the late 1980's in the southern tip of India in the Kallemedu Formation northeast of Kallamedu village.After it's discovery it was thought to be a theropod dinosaur like Allosaurus. But some scientists told that if it did exist it has to be a titanosaur. However, soon after discovery, these remains were lost to a monsoon. Only the original description and line drawing of the hip and leg bones remain to represent it ever existed at all.

Size estimates[]

According to the published description, the tibia (shin) of Bruhathkayosaurus is two meters (6.56 feet) long, and the fragmented femur is 75 centimeters (2.46 feet). Due to the lack of skeleton, the length, weight, and height of the creature is mostly speculation, and estimates have varied greatly. No size estimates has ever been published but some estimates have been published in internet. Some paleontologists from Los Angeles in 1996 estimated it's size to be 30 meters. But in 2008, a paleontologist estimated it's size to be 40-44 m but again he said his previous estimation was wrong and the real size was 28–34 m.But the first size estimation was mainly accepted by media and public. It seems to be inferred that Bruhathkayosaurus would have had a very bulky build and would have been much heavier than other sauropods.

It's size has been estimated at 28 meters, which is longer than the sauropods like Brachiosaurus. Bruhathkayosaurus was probably the largest dinosaur ever found in India, so far.

More recent estimates was conducted after new unclassified images of Bruhathkayosaurus emerged. A 2022 review by Pal and Ayyasami had confirmed that the skeleton photos were real, the genus is likely valid and that the sauropod likely existed after all. These new photos bared light on additional estimations. In 2019, Gregory S Paul gave estimations that Bruhathkayosaurus likely tipped the scales at around 80-120 tons and was 35-40 meters long. In 2023, Gregory Paul and Asier Larramendi collaborated on a new scale. By using various sauropods of different built and design as a template, they estimated that Bruhathkayosaurus would have weighed as much as 170 tons maximum, rivaling the largest Blue Whale in scale. Although more realistic measurements still placed it between 110-130 tons. If these estimates were accurate, it would place Bruhathkayosaurus by far the largest terrestrial animal to have ever lived and rivaled the largest Blue Whales in existence.
