Mature blue whales can reach 30 m (98 ft) in length, and the record-holder blue whale was recorded at 173 tonnes (190 short tons), [23] with estimates of up to 199 tonnes (220 short tons). [24] Another poorly known sauropod that shares similar size estimates to Bruhathkayosaurus is Maraapunisaurus fragillimus, which is based on a now-missing ...
The heaviest blue whale on record weighed 190 metric tons (190 long tons; 210 short tons), [12] and the heaviest dinosaur known from reasonably good remains, Argentinosaurus, weighed 80 to 100 metric tons (79 to 98 long tons; 88 to 110 short tons), although if the size estimates can be validated, it could still be lighter than Bruhathkayosaurus ...
At the time, mass estimates ranged up to 180 tons, [14] which placed it in the same category as the blue whale and the equally problematic Bruhathkayosaurus. The naming of the chimeric Ultrasauros has a similarly complicated history. Ultrasaurus (with the final "u") was the original choice, and was widely used by the media after the discovery ...

Meanwhile, 'mega-sauropods' such as Bruhathkayosaurus has long been scrutinized due to controversial debates on its validity, but recent photos re-surfacing in 2022 have legitimized it, [28] allowing for more updated estimates that range between 110–170 tons, rivaling the blue whale in size. [29]
Perucetus is the largest Eocene whale measuring about 17–20 meters (56–66 ft) long. Some researchers claim that it may have rivaled or exceeded the modern blue whale in weight, partly due to the incredibly thick and dense bones this animal possessed, coupled with its already great size, while others argue that it was much lighter.
