Triassic Kraken Lair?

This is strong supportive evidence of the existence in Triassic times of a giant octopus or kraken capable of killing forty five foot whales or their equivalent.  That they could is shown from comparables in the noted shark tank.  I probably ate far more sharks than whales.

It appears reasonable that such a creature could well have lived into recent times and could well have been seen in the days of sail.  Our problem today is simple.  We make way too much noise.  For that reason large creatures who rarely actually surface such as the kraken and the sea serpent are simply never going to be seen.

This creature and the sea serpent both operate from the deep and likely prey on large fish such as sharks operating at similar depths.  Since we have nothing that will accidentally capture such creatures, we don’t.

Both the sea serpent and the kraken will be long lived and will occupy large territories.  The population should then be global and a lot larger than we expect.

So though we like to think that these two animals are mythical, their habitat is completely foreign to our own and the prospect for interaction is likely limited to the time of procreation when other behavior takes over to betray them to our eyes.

I thing it is safe to add the kraken to our list of plausibly living beasties.

It goes without saying that an octopus that is a hundred feet long is quite capable of seizing a small sailing vessel and causing it to capsize.  There is more than enough here to substantiate seamen's stories from the past.

Lair of Ancient 'Kraken' Sea Monster Possibly Discovered

By Jeanna Bryner | – 4 hours ago

A giant sea monster, the likes of the mythological kraken, may have swum 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, 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 is scheduled to present his work Monday (Oct. 10) at the annual meeting of the Geological Society of America in Minneapolis.

Cause of death

Evidence for the kraken and its gruesome attacks comes from markings on the bones of the remains of nine 45-foot (14 meter) 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.

Mark McMenamin, a paleontologist at Mount Holyoke College in Massachusetts 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, and recent work on the rocks around the fossils suggests they died in a deepwater environment, McMenamin said.

"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 octopus.

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. Video taken by staff at the Seattle Aquarium showed that a large octopus in one of their large tanks had been killing the sharks.

"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.

Though his case is circumstantial, and likely to draw skepticism from other scientists, McMenamin said: "We're ready for this. We have a very good case."
