In what is called a "surprising discovery", scientists in Antarctica have conserved conservative boxes of small, old animals that have been buried for thousands of years in a mere over 3,500 meters of ice.
The discovery of dead Christmas ratings and tardigrades, also called "water berries" or "marshland", was made by a team of American researchers on a mission to build Mercer Subglacial Lake, about 400 miles from the Antarctic, Nature.
The discovery of the small, ancient animals was "completely unexpected", said David Harwood, a micro-palaeontologist at the University of Nebraska-Lincoln who is part of & # 39; e expedition, known as SALSA (Sub-glacial Antarctic Lakes Scientific Access).
After spending days with thick ice creams, the SALSA team sent an instrument on December 28 to capture rare footage of captive, science-based and collect samples. After six days of sampling, they have told researchers that they have enough "material for the way we look at the Antarctic continent", in a SALSA blog post.
Researchers told at least some of Lake Mercer's animals were landscapes. The eight legendary tardigrade seems to look like species known to live on wet soil, according to Nature.
The creators are beliefs that inhabited pounds and streams inhabited in the Transantarian mountains, some 31 kilometers from Lake Mercer, in short warm periods where the glaciers returned – both in & # 39; The past 10,000 years, or 120,000 years ago. Later, when the climate cooled, it hit the ice of animal life.
"That's really nice," says Slawek Tulaczyk, a glass soloist at California University, Santa Cruz, who is not a part of & # 39; a SALSA team. "It's definitely surprising." Tulip, which has reached a sedimentation of glacial ice during the seventh century Nature No one like that ever found for the leaflet.
Mercer Subglacial Lake Mercer was discovered more than ten years ago by satellite images, but has never been discovered. It is one of 400 Antarctic ice-cream lakes, and experts say any hope of catching up with comparable organisms can be found deep within Mars or at & # 39; a bloodthirsty months of Jupiter and Saturn.
Scientists will now be hoping to find & # 39; discovering creatures & # 39; Get DNA, find out more about how far, and how far, Antarctica's glaciers are pulling for millions of years. Sequential scraps of DNA from carcasses, mouth, and water can also determine which custody states belong to marine or gypsy waters.
