Now, I’ve seen skeletons of Argentinosaurus before, but nothing can prepare you for the sheer immensity of this dinosaur in the flesh.

These titanic sauropods (fittingly called titanosaurs) grow rapidly. Once they reach a certain size, they are virtually untouchable and have nothing to fear from puny apex predators. Hungry guests, though? Let's hope we don't find out!

A single vertebrae from the back of this animal could be over a meter and a half tall!

Hatchlings are absolutely puny by comparison. Without the protection of enormity, young Argentinosaurus are extremely vulnerable so adults compensate by having as many babies as possible to increase their chances that one of them will reach adulthood. Quantity over quality!
