The huge and powerful marine monster would have been outcompeted for resources by smaller and nimbler rivals. Evidence comes from its tiny placoid scales – the first discovery of its kind
Megalodon – the biggest shark that ever lived – was wiped out because it was too slow, according to new research. It was not as fast as believed but had a mega-appetite – explaining its gigantism, say scientists.
The huge and powerful marine monster would have been outcompeted for resources by smaller and nimbler rivals. Evidence comes from its tiny placoid scales – the first discovery of its kind.
They lacked narrowly-spaced ridges or ‘keels’ – characteristic of fast-swimming fish.
Lead author Professor Kenshu Shimada, of DePaul University in Chicago, said: “This led my research team to consider O. megalodon to be an ‘average swimmer’ with occasional bursts of faster swimming for prey capture.”
