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 ...
The previously mentioned antarctic blue whale holds the title of the biggest animal on earth. It can weigh up to 400,000 pounds and reach a length of 98 feet. It can weigh up to 400,000 pounds and ...
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]
Balaenoptera sibbaldii Sars 1875. The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale. Reaching a maximum confirmed length of 29.9 m (98 ft) and weighing up to 199 t (196 long tons; 219 short tons), it is the largest animal known ever to have existed. [a] The blue whale's long and slender body can be of various shades ...
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds, which can weigh as little as two grams, to the extinct titanosaurs, such as Argentinosaurus & Bruhathkayosaurus [1] which could weigh as much as 50–130 t (55–143 short tons).
