Liquid blood and urine were found in a 42,000-year-old prehistoric foal



The animal's body fluids were extracted during an autopsy and tested in the hope of cloning the extinct species, as Semyon Grigoriev, director of the Northeastern Federal University's (Mammoth) Museum in Yakutsk, discovered. The age-old foal was in summer Embedded in the permafrost of the massive Batagaika crater in 2018, on a day when the temperature had dropped to -67.8 degrees Celsius.

Grigoriev emailed CNN that the foal had turned up Just two weeks old when it died, probably by drowning in the mud, which then became part of the permafrost.

"An autopsy showed that the foal carcass was extremely well preserved, the body even without deformation," he added. "The hair cover also kept most parts of the carcass, especially on the head and legs."

The conservation of the animal's fur was extremely rare, Grigoriev said before adding, "Now we can tell what color the wool of the extinct horses of the Pleistocene era."

The discovery of liquid blood and urine is even rarer. Grigoriev said he only knew of another case in which liquid blood was found in a Pleistocene animal that lasted about 2.6 million years ago until about 11,700 years ago. It was in the frozen carcass of an adult mammoth that Grigoriev's team had discovered in May 2013 on Little Lyakhovsky Island off the northeast coast of Russia.

"In the fossil remains of animals of the Ice Age, the blood usually clots in powder form or even turns into powder, even if the carcass is preserved, it seems to be good," explained Grigoriev. "This is due to the mummification process when moisture and other biological fluids gradually evaporate over millennia, even if the remains are in permafrost, and the remains are best preserved when they are in ice, as was the case with our mammoth .

Grigoriev said the NEFU specialists worked with experts from the controversial South Korean Sooam Biotech Research Foundation to cultivate the foal's cells for cloning he was pessimistic about their chances.

Sooam is led by scientist Hwang Woo-suk, who claimed in 2004 that he had successfully cloned human embryonic stem cells before admitting that he had falsified his findings.

"I even think Unique Conservation [of] Blood is absolutely hopeless for cloning purposes because the main blood cells – the red blood cells or erythrocytes – have no nuclei with DNA," said Grigoriev. "We [are] are trying to find intact cells in muscle tissue and internal organs that are also very well preserved."

The old horse will be shown throughout Japan from June to September 2020 as part of the Mammoth exhibit.
