Intriguingly, tests on Dreadnoughtus’ bones didn’t uncover any telltale signs of ageing, which are usually found in animals that have reached their growth limit. This 85-foot-long monster, then, was probably getting bigger when it died.
Dreadnoughtus was, in fact, a herbivore. It used its massive neck to reach food, and scientists believe that it would have had to eat almost constantly to sustain its huge size. But while its enormity and strong tail meant that predators probably left it alone, this giant wasn’t without its problems.
