Evidence of a giant sea monster, the mythological Kraken – twice as big as a colossal squid – has been discovered.

One of the sea’s top ancient sea predators may have been found -  a school bus-size ichthyosaurs with fearsome teeth.

The kraken, typically over 100 feet  long, or twice the size of the colossal squid, Mesonychoteuthis, most likely drowned or broke the necks of the ichthyosaurs before dragging the corpses to its lair, akin to an octopus’s midden, according to study researcher Mark McMenamin, a paleontologist at Mount Holyoke College in Massachusetts.

There is no direct evidence for the beast, though McMenamin suggests that’s because it was soft-bodied and didn’t stand the test of time; even so, to make a firm case for its existence one would want to find more direct evidence.

McMenamin presented his work Monday (Oct. 10) at the annual meeting of the Geological Society of America in Minneapolis.

Evidence for the kraken and its gruesome attacks comes from markings on the bones of the remains of nine 45-foot ichthyosaurs of the species Shonisaurus popularis, which lived during the Triassic, a period that lasted from 248 million to 206 million years ago. The beasts were the Triassic version of today’s predatory giant squid-eating sperm whales,

McMenamin was interested in solving a long-standing puzzle over the cause of death of the S. popularis individuals at the Berlin-Ichthyosaur State Park in Nevada. An expert on the site, Charles Lewis Camp of U.C. Berkeley, suggested in the 1950s that the ichthyosaurs succumbed to an accidental stranding or a toxic plankton bloom. However, nobody has been able to prove the beasts died in shallow water, with more recent work on the rocks around the fossils by Jennifer Hogler, then at the University of California Museum of Paleontoloy, suggesting they died in a deepwater environment.

“I was aware that anytime there is controversy about depth, there is probably something interesting going on,” McMenamin said. And when he and his daughter arrived at the park, they were struck by the remains’ strangeness, particularly “a very odd configuration of bones.”

The etching on the bones suggested the shonisaurs were not all killed and buried at the same time, he said. It also looked like the bones had been purposefully rearranged, likely carried to the “kraken’s lair” after they had been killed. A similar behavior has been seen in modern octupus.

The markings and rearrangement of the S. popularis bones suggests an octopus-like creature (like a kraken) either drowned the ichthyosaurs or broke their necks, according to McMenamin.

The arranged vertebrae also seemed to resemble the pattern of sucker disks on a cephalopod’s tentacle, with each vertebra strongly resembling a sucker made by a member of the Coleoidea, which includes octopuses, squid, cuttlefish and their relatives. The researchers suggest this pattern reveals a self-portrait of the mysterious beast.

The perfect crime?

Next, McMenamin wondered if an octopus-like creature could realistically have taken out the huge swimming predatory reptiles. Evidence is in their favor, it seems.

“We think that this cephalopod in the Triassic was doing the same thing,” McMenamin said. More supporting evidence: There were many more broken ribs seen in the shonisaur fossils than would seem accidental, as well as evidence of twisted necks.

“It was either drowning them or breaking their necks,” McMenamin said.

So where did this kraken go? Since octopuses are mostly soft-bodied they don’t fossilize well and scientists wouldn’t expect to find their remains from so long ago. Only their beaks, or mouthparts, are hard and the chances of those being preserved nearby are very low, according to the researchers.

With such circumstanial evidence of “the crime,” McMenamin expects his interpretation will draw skeptics. And, in fact, it has. Brian Switek, a research associate at the New Jersey State Museum,  is extremely skeptical, writing, “The McMenamins’ entire case is based on peculiar inferences about the site. It is a case of reading the scattered bones as if they were tea leaves able to tell someone’s fortune. Rather than being distributed through the bonebed by natural processes related to decay and preservation, the McMenamins argue that the Shonisaurus bones were intentionally arrayed in a ‘midden’ by a huge cephalopod nearly 100 feet long” (McMenamin worked with his wife, Dianna Schulte McMenamin on the study.)

As for how McMenamin would respond to critics: “We’re ready for this.  We have a very good case.”

MARTHA’S VINEYARD, MA – The Obama family began their week-long vacation this weekend. The Kraken at the heart of Hurricane Bill was diverted out to sea to avoid any complications.

Like many hurricanes, Hurricane Bill was caused by an angry kraken who had been woken from his slumber.  Unconfirmed reports say the filming crew of a Discovery Planet fishing show was responsible for awakening the beast.  As the monster raged, a category 3 hurricane grew around him.

Given the already overstretched government resources, and the Presidential vacation set to begin Sunday night, officials were willing to take drastic action to veer the monster further away from shore.  “Well, it wasn’t easy” said Mike Angiakis, FEMA specialist on Sea Monsters.  “But when you consider the alternative, there really wasn’t a choice.”

Dozens of government helicopters airlifted 50 thousand of pounds of dead fish leading the monster out to sea.  Coating the fish was 16 thousand pounds of tsatziki sauce, which “krakens are highly partial to” says Angiakis.  The yogurt seasoned fish stretched for miles into the Atlantic in a line that could be seen from space.

Hurricane Bill’s path had been following the US East Coast northward, causing storms and tidal disturbances.  Thanks to the sudden change in course it avoided any landfall in the northern US and the Obama vacation in Massachusetts was able to proceed without incident.

Some are wondering if the government only stepped in with this hurricane to assist in the President’s vacation.  “Preposterous!” said Angiakis.  “The government dealt with this sea monster because it was the right thing to do!”

The kraken is believed to have been sated by the massive meal, and is currently hibernating off the coast of Greenland.

NEW YORK, NY – Following three years of repair, the USS Intrepid’s return to Manhattan was greeted by the Tri-State Area’s only known Kraken.

The decommissioned WWII battleship returns to its dock, reopening the Intrepid Sea, Air, and Space Museum. Spectators were delighted as the Battleship approached the city, and even more surprised when Grakkle the Kraken emerged in dramatic fashion sending waves crashing over the Intrepid.

Executive Director of the Intrepid Museum, Susan Marenoff commented, “It was such a pleasure to have Grakkle rise in honor of the Intrepid’s return. We had no idea he was in the area, or a fan of the museum. We’re hoping to have him participate in an upcoming exhibition on the role of US Warships in the Kraken-Great Squid Battle of 1948.”

Viewers were treated to a nautical display not seen in recent decades. While Grakkle was once a common site along the coast of Manhattan, Coney Island, and the Long Island Sound, he been much more reclusive as of late.

“I was delighted to see two of New York City’s treasures together,” New York City Mayor Michael Bloomberg told reporters, “but my fear is that the rise of Grakkle is a portent for something brewing under the waters of New York. We really cannot afford another Kraken outlash against our trade ships. Not in this economy.”
