Long before whales, the oceans of Earth were roamed by a very different kind of air-breathing leviathan. Snaggle-toothed ichthyosaurs larger than school buses swam at the top of the Triassic Period ocean food chain, or so it seemed before Mount Holyoke College paleontologist Mark McMenamin took a look at some of their remains in Nevada. Now he thinks there was an even larger and more cunning sea monster that preyed on ichthyosaurs: a kraken of such mythological proportions it would have sent Captain Nemo running for dry land.The peculiarities ensued when a graveyard of icthyosaurs was discovered arranged in a non-random order and with odd markings on them:
‘What-if?’ stories are great fun and thought provoking but a great deal more evidence will have to be amassed before this can be verified/supported. Given the size of some of the creatures in the past (here, here and here) however, this is not so hard to believe.
