In what period did the largest known animal ever live?
Jurassic
Triassic
Cretaceous
Quaternary (now)
At 190 tonnes in weight, blue whale is the largest known animal ever to have existed. The tallest and heaviest sauropod known from a complete skeleton weighed 23–37 tonnes. There were much larger sauropods, but they are known from only a few bones, and it is unlikely they matched a blue whale.
