The cavern sits where nearly 14 billion tons of ice used to be, all of which melted in the last few years. Geologists taking sediment cores from the seafloor beneath the giant Filchner-Ronne Ice Shelf on the southern edge of Antarcticas Weddell Sea discovered what biologists believe are types of sponge. The video was titled 'Antarctica Melting Ice MAY have revealed ANCIENT skeletal remains fully INTACT! The "dragon-skin" sighting was an early highlight of the expedition, because the rare ice formation had not been seen in Antarctica since 2007, the researchers said. Mining is illegal in Antarctica due to the Antarctic Treaty. After lowering the sediment corer through the borehole, the scientists then lowered it through about 1,600 feet of seawater below the floating ice shelf. It was discovered by the British Antarctic Expedition of 1910-1913. Discovered in 2010 in Montanas famed Hell Creek Formation of the late Cretaceous, the 40-foot-long fossil took four years to excavate and prepare. It's thought both types of stationary animals are types of sponges or are related to sponges, but scientists did not expect to find them beneath the ice shelf, in pitch-blackness and hundreds of miles from the coast. The excavation finally finished in 2017, yielding a substantial portion of the animals skeleton, which OGorman and his colleagues describe in their recent paper in Cretaceous Research. With 170 of its 300-odd bones preserved, this scientifically important but privately owned skeleton is currently at the Museum fr Naturkunde in Berlin, Germany. There is a 9- to 10-meter wingspan azhdarchid in this formation; whether or not thats exactly the same as the one weve described, you cant say 100-percent, Hone says. Multiple expeditions in the 19th century managed to reach the Antarctic Peninsula, and in 1911 Roald Amundsens party were the first people to reach the South Pole. Scientists may have found something unfathomably massive living under I love these critters. The partial skeleton that defines Cryodrakon was dug up from Canadas Dinosaur Provincial Park in 1992. These underwater terrors can grow up to have a leg span of 25 centimeters. Two key advances offered a way off the Quetzalcoatlus merry-go-round. And when Habib, Hone, and Royal Tyrrell Museum paleontologist Franois Therrien compared the holes in the Canadian pterosaurs neck vertebrae against those for all other known azhdarchids, they found that its arrangement is unique.
