It sounds completly crazy. But it’s what a group of paleontologists are claiming — the first sentient beings on Earth to create art may not have been humans, but monstrously large, tentacled sea creatures called “kraken” who lived 200 million years ago and possibly arranged bones in geometric, decorative patterns. io9 explains further:
For decades, paleontologists have puzzled over a fossil collection of nine Triassic icthyosaurs (Shonisaurus popularis) discovered in Nevada’s Berlin-Ichthyosaur State Park. Researchers initially thought that this strange grouping of 45-foot-long marine reptiles had either died en masse from a poisonous plankton bloom or had become stranded in shallow water.
But recent geological analysis of the fossil site indicates that the park was deep underwater when these shonisaurs swam the prehistoric seas. So why were their bones laid in such a bizarre pattern? A new theory suggests that a 100-foot-long cephalopod arranged these bones as a self-portrait after drowning the reptiles. And no, we’re not talking about Cthulhu.
After considering the more brutal aspects of modern octopus predation, paleontologist Mark McMenamin of Mount Holyoke College came to the conclusion that the shonisaur remains had been deposited in a “kraken” lair by its massive, tentacled squatter:
We hypothesize that the shonisaurs were killed and carried to the site by an enormous Triassic cephalopod, a “kraken,” with estimated length of approximately 30 m, twice that of the modern Colossal Squid Mesonychoteuthis. In this scenario, shonisaurs were ambushed by a Triassic kraken, drowned, and dumped on a midden like that of a modern octopus. Where vertebrae in the assemblage are disarticulated, disks are arranged in curious linear patterns with almost geometric regularity.
