'Bizarre,' Huge Sea Scorpion Found in Ancient Meteorite Crater

'Bizarre,' Huge Sea Scorpion Found in Ancient Meteorite Crater

      About 460 million years ago, a sea scorpion about the size of an adult human swam around in the prehistoric waters that covered modern-day Iowa, likely dining on bivalves and squishy eel-like creatures, a new study finds.

The ancient sea scorpions are eurypterids, a type of arthropod that is closely related to modern arachnids and horseshoe crabs. The findings — which include at least 20 specimens — are the oldest eurypterid fossils on record by about 9 million years, said study lead researcher James Lamsdell, a postdoctoral associate of paleontology at Yale University.

Scientists Descend into Mysterious Siberian Crater (2) - Nov 2014

Haunting beauty of massive hole as scientists examine frozen lake formed after giant blowout.

     A mission this week to the newly-formed crater on the Yamal Peninsula in northern Siberia is expected throw fresh light on how this and other such phenomenon were formed. Experts are working on a theory that gas hydrates caused underground explosions in the same way as eruptions under the Atlantic Ocean may have led to the Bermuda Triangle phenomenon.

Our new pictures show how, for the first time, scientists used climbing equipment to reach the base of the crater - a lake at least 10.5 metres deep with a frozen surface.

Leader of the new mission, Vladimir Pushkarev, director of the Russian Centre of Arctic Exploration, told The Siberian Times: 'We managed to go down into the funnel, all was successful. We used climbing equipment, and it is easier to do this in winter, than in summer, with the ground now hard.

'We took all the probes we planned, and made measurements. Now scientists need time to process all the data and only then can they draw conclusions.'

The funnel of the crater is about 16.5 metres deep, not including an earthen rampart on the surface, formed in the blowout, of several metres in height. . . .

Reindeer herders find more craters in the far north in a deepening puzzle for scientists.

    Millions of people around the world glimpsed the first giant hole after it was revealed by The Siberian Times . . .. Now news has emerged of two new similar formations in the permafrost, prompting more intrigue about their creation.

Theories range from meteorites, stray missiles, a man-made prank, and aliens, to an explosive cocktail of methane or shale gas suddenly exploding. The version about melting permafrost due to climate change, causing a release of methane gas, which then forces an eruption is the current favorite, though scientists are reluctant to offer a firm conclusion without more study. . . .

First Pictures From Inside of Mysterious Giant Hole in Siberia - July 2014

     Experts examine the newly-discovered hole in the earth in Siberia.

The crater on the Yamal Peninsula was caused by aliens, a meteorite, a stray missile, or an explosive gas cocktail released due to global warming, according to various theories in recent days.

Images of the remarkable phenomenon have gone round the world since The Siberian Times highlighted helicopter images of the giant hole earlier this week.

The first expedition to the scene - the scientists have just returned - took these epic pictures of the hole, including the darkening pattern on the inner rim.

Now they are using Russian satellite pictures to fix the moment when it suddenly formed.

They found the crater - around up to 70 metres deep - has an icy lake at its bottom, and water is cascading down its eroding permafrost walls. . . .
