Truly gigantic squids, long known in myth as the Kraken, were thought to be only myth, even though modern evidence suggests living giant squids up to 20m long are possible.
The later Peter Benchley once wrote that a prominent teuthologist who asked not to be named would not be surprised if a 40m squid turned up. Now from the world of paleontology comes the suggestion that such giants lived a very long time ago. It's circumstantial evidence - a collection of bones of huge, apparently violently killed 14-m icthyosaurs from over 200 million years ago - but paleontologist Mark McMenamin thinks it's the logical explanation.
COMMENT: Expect a lot of pushback - he's making a very dramatic claim without hard evidence for it. But if he's willing to advance and defend his work, then who knows what others may find pursuing this lead and looking for better evidence?
