![]() In 1929 Matley described some large bones and suggested they were from a titanosaur, “although he was not able to extract any bones, even with the greatest care” (they were very fragmentary).Blanford was the first to report large dinosaur bones from the formation, in 1862 Thought Bruhathkayosaurus to be a sauropod based on the fossils “exceptionally large dimensions”.In 2022 Pal and Ayyasami reviewed the material and found the skeleton was real and Bruhathkayosaurus was probably valid.Later studies found Bruhathkayosaurus to be an indeterminate sauropod or nomen dubium.In 1995 Chatterjee re-analyzed the fossils and found Bruhathkayosaurus to be a titanosaur.Originally thought to be a carnosaur theropod, similar to Allosaurus.Some researchers thought the fossils were petrified wood because of the large size, and some thought the find was a hoax.Original description had a few line drawings and photographs of the fossils at the dig site, and there were not many descriptions of its unique features.(Holotype no longer here, similar to Amphicoelias, which we covered in episode 413).Fossils in the soft sandstone get water-saturated during monsoon season and dry in the summer when it’s intensely hot, which contributes to the “crumbly nature of the bones”. ![]() Said the fossils from the Kallamedu Formation are “very friable in nature”.Fossils started “disintegrating in the field jackets and crumbled to dust before reaching the repository of the Geological Survey of India, Hyderabad”, according to Saurabh Pal and Krushnan Ayyasami in 2022.Ayyasami described Bruhathkayosaurus in 1987 Then in the dry season, fossils may expand in the day and contract at night. Monsoon season, with sands and clays from the formation, saturate them with water. Fossils from the Kallamedu Formation are not well preserved. ![]()
