A new, updated Walking With Dinosaurs is back on the BBC this weekend .

In the intervening years , science has not stood still.

About 50 species have been discovered each year since 1999 and the advent of powerful imaging techniques and digital reconstruction have led to major advances in our understanding of what dinosaurs looked like and how they lived.

Spinosaurus is longer than any other meat-eating dinosaur, has conical teeth like those seen in crocodiles, a long newt-like tail and dense bones that might help it sink in order to swim underwater.

Computer simulations have raised questions about its hydrodynamic properties, with one suggesting it would have rolled over on its side when submerged.
