Well, animals her size and weight must have moved in a rather ponderous way.

And in any case, since she was a vegetarian, as we know from her teeth, she had no need to be speedy to get her food.

But it's the tiny bones in Dippy's inner ear that can give us a clue as to what she sounded like.

These little bones are basically the same shape

as that of the dinosaur's closest relatives, birds.

is related to its size, a small bird makes and hears high-pitched sounds.

Whereas large birds communicate with low-pitched sounds.

So huge Dippy, with her inner ear bones shaped like those of a bird, could probably hear very low pitched frequencies of sound.

We know that elephants today can communicate using infrasound.

Sound with frequencies so low, they're below human hearing, and those sounds travel through the ground, sometimes for many miles and are detected by elephants through their large flat sensitive feet.

So maybe the giant dinosaurs communicated with one another in much the same way, as well as by bellowing.

Her long tail would have helped to balance her long heavy neck.

The most likely explanation seems to be that it helped her to reach leaves in all sorts of difficult places.

But in order to reach the highest, most succulent leaves in the forest, it seems likely that Dippy would have reared up on her hind legs.
