A giant sea monster, the likes of the mythological kraken, swam Earth's ancient oceans, snagging what was thought to be the sea's top predators — school bus-size ichthyosaurs with fearsome teeth.
The kraken, which would've been nearly 100 feet (30 meters) long, or twice the size of the colossal squid, Mesonychoteuthis, drowned or broke the necks of the ichthyosaurs before dragging the corpses to its lair, akin to an octopus's midden, as proven by study researcher Mark McMenamin, a paleontologist at Mount Holyoke College in Massachusetts .
