as they lay in the ground. This led to online speculation by researchers that the bones might actually have been petrified wood, akin to the way the original discoverers of Sauroposeidon initially believed their find to be fossilized tree trunks,. However, a 2022 review by Pal and Ayyasami suggested that the skeleton was real and that the genus is likely valid. Additional previously unseen photographs were provided of the tibia bone at the excavation site and in a plaster jacket. Pal and Ayyasami also reinforced the taxon's position within Titanosauria. The only known remains of Bruhathkayosaurus have been lost so the validity of the genus and any size estimates are questionable. Size estimates According to the published description, the shin bone (tibia) of Bruhathkayosaurus was long. This is 29 percent larger than the tibia of Argentinosaurus, which is only long. The fragmentary femur was similarly huge; across the distal end, it measured , 33% larger than the femur of Antarctosaurus giganteus, which measures . The ilium measured in length. No total body size estimates for Bruhathkayosaurus have been published, but paleontologists and researchers have posted tentative estimates on the Internet. In a post from June 2001, Mickey Mortimer estimated that Bruhathkayosaurus could have reached in length and might have weighed , but in later posts retracted these estimates, reducing the estimated length to based on more complete titanosaurs (Saltasaurus, Opisthocoelicaudia and Rapetosaurus), and declined to provide a new weight estimate, describing the older weight estimates as inaccurate. In a May 2008 article for the weblog Sauropod Vertebra Picture of the Week, paleontologist Matt Wedel used a comparison with Argentinosaurus and calculated the weight of Bruhathkayosaurus at up to . In 2019, Gregory S. Paul suggested that the supposed tibia was probably a degraded femur, in which case its length was slightly greater than that of Dreadnoughtus (1.91 meters) and Futalognkosaurus (1.98 meters). Its ilium is similar in length to that of Dreadnoughtus whereas the width of the distal femur appears to slightly exceed that of Patagotitan. Paul estimated its mass at around , much lower than any previous estimation. In 2020, Molina-Perez and Larramendi suggested that the long tibia is probably a fibula, and estimated the size of the animal at and . By comparison, the titanosaur Argentinosaurus is estimated to have reached in length, and to have weighed 65–100 tonnes. These sauropods are known only from partial or fragmentary
