If the upper estimates of the 2023 records are accurate, Bruhathkayosaurus may have rivaled the blue whale as one of the largest animals to ever exist. However, all of the estimates are based on the dimensions of the fossils described in 1987, but these fossils have since disintegrated and no longer exist, making it impossible to affirm these estimates.
