The team found during one of the Antarctic expeditions prints guttate strange creatures and amazing animals with hard tails. According to the researchers, these organisms seem to have been only exist in a very warm climate and warm sea water. Experts say that they had found the remains indicate that the animal is a cross between modern leeches and amoebas, but their size is closer to the latter. On fossilized prints clearly visible internal structure of animals: here in the presence of a fairly complex set of biological structures: cells with nuclei, flagella and relatively robust housing that covers the inside of the body. According to researchers, lived all these animals in the Antarctic later period, when the temperature was higher than the current rates.The fact that it was higher science known, but given that even in very high latitudes warm-lived creatures, may indicate that the climate was hotter than assumed.
At a time when discovered creature lives on the planet, Antarctica has not been an independent continent, and was part of the ancient supercontinent of Gondwana, but even then the proto-Antarctica was in high latitudes, it is believed that a hot climate there had never been ,found the ancient inhabitants Antarctica had a small size from 25 microns to several millimeters. It is believed that they lived in those circumstances, when the future South Pole of the planet was a temperate continental zone, where trees grew, was a humid climate.
However, it is believed that it was not hot. The new findings also suggest that at least part of the year there were hot. surprising experts call the fact that fossils could reach up to now, because in the process they have been storing a variety of different conditions and had all the chances completely destroyed. "We still can not understand how such a soft-bodied organisms were able to leave footprints in solid rock, as usual, if they are buried in the soft environment, is their rapid destruction," - said Benjamin Bomfler Institute of Biodiversity at the University of Kansas.
According to where prehistoric organisms died, in the territory of proto-Antarctica, they were on the soft rock, such as leaves, dirt or loose soil. Then is it has morphed into a modern stone-coal rock. The question is, why soft body does not break for more than 200 million years. The researchers believe that this could contribute to an alkaline environment created around the body as a kind of cocoon. Previously, researchers have found something similar on the Norwegian part of Spitsbergen. There they found nematodes, which were in their biological cocoons at least 125 million years.
