The Great Arctic Basilisk is one of the earths natural cooling mechanisms from the days when giant beasts roamed. Beginning from a small egg, the creature grows to an improbable 3000 feet long, absorbing any heat from the environment around it. The basilisk makes its way into the ocean, where it supercools the water, suspending natural currents and halting atmospheric heat transfer. Eventually it lays a clutch of eggs, preserved in a frozen shell that preserves the next generation for millennia. According to fossil records, the creatures last thawed during the extreme warming event at the end of the Cenozoic period, dominating the northern pole and triggering the ice age lasting through the start of the Holocene period. Theyre not due for another 6,000 years, but scientists report the timetable may need to be moved up.
