Okay,I looked it up an there were different results

Yeah, its outdated

I like how all Prehistoric stuff are larger and then there's the Blue Whale

^Perucetus

But that isn't confirmed

^^^ the only W modern day has size-wise

^^^Perucetus is 68-90 Tonnes iirc

Please be 69 tons

Nankangia weighs 69 kg.

Good enough
