Maybe, sad that most of them are very fragmentary/lost. I hope we discover more soon.

^^Sauropods physically couldn’t reach Blue Whale size

The most reliable size for Argentinosaurus is 75 Metric Tons, not even as much as Sperm Whales, which(At minimum) reach 20.7 Meters and 80 Tonnes, with potential 24 Meter, 110 Tonne, and 28 Meter, 150 Tonne individuals

Blue whales physically can't grow to 33 meters in length and 200 tons in weight either

^^ didn't we think the same for sauropods until we found the Titanosaurs like Argentino?

I wouldn't say its impossible we are still missing animals larger than Argentinosaurus since sauropod skeletons are near impossible to properly preserve

^^They can lmao

The 33 meter length estimate was debunked

They still reach 28 Meters and 190 Tonnes

So 33 Meters and 240 Tonnes isn’t unreasonable

This paper cites a female blue whale that was ~ 27.6 meters in length, and weighed 190 tonnes, still reliably larger than any sauropod (granted, this particular female was robust and thus weighed more, but it still counts regardless)

Wouldn't pregnant whales get even heavier? I assume, though, that they'd be ignored in these kind of records since it'd really just be weighing 2 whales
