PREHISTORIC Earth was a place of monsters. There were 2.5-metre-long millipedes, flying reptiles with 11-metre wingspans and snakes that weighed over a tonne. But if it is the biggest animal of all time you are looking for, conventional wisdom says you don’t need to step back in time. The blue whale is known to

Conventional wisdom might be wrong. The fossil record may be concealing an animal that was even ******* than a blue whale. For decades there has been a slow trickle of evidence that a truly enormous super-predator swam the seas between 200 and 250 million years ago. Now, a string of discoveries and reanalysis of previous findings has dramatically bolstered the case.

The implications are far-reaching. We don’t know exactly what this huge animal looked like and it doesn’t even have a name. We have, however, begun to work out how such a gigantic creature could feed itself in the prehistoric seas. Confirmation that it outgrew the blue whale would tell us that we may have drastically underestimated how large toothed carnivores can grow. More than that, the discovery that such leviathans appeared shortly after the most devastating mass extinction in Earth’s history suggests we may need to rethink the factors that drive evolution on such an epic scale.

When dinosaurs ruled the land, several groups of marine reptiles dominated…
