mammoth fossil

Fossilized remains of a woolly mammoth.

An 11year old boy in Russia made quite the discovery. He came across a well preserved fossil of an adult woolly mammoth. From BBC News:

The remains were discovered at the end of August in Sopochnaya Karga, 3,500km (2,200 miles) northeast of Moscow.

A team of experts from St Petersburg then spent five days in September extracting the body from frozen mud.

The mammoth is estimated to have been around 16 years old when it died; it stood 2m tall and weighed 500kg.

It has been named Zhenya, after Zhenya Salinder, the 11-year-old who found the carcass while walking his dogs in the area.

Alexei Tikhonov, from the St Petersburg Zoology Institute, who led the team excavating the mammoth, said this specimen could either have been killed by Ice Age humans, or by a rival mammoth.

He added that it was well preserved for an adult specimen.

His colleague Sergei Gorbunov, from the International Mammoth Committee, which works to recover and safeguard such remains, said: “We had to use both traditional instruments such as axes, picks, shovels as well as such devices as this “steamer” which allowed us to thaw a thin layer of permafrost.

“Then we cleaned it off, and then we melted more of it. It took us a week to complete this task.”

cloning a woolly mammoth

Its a story straight out of Jurassic Park! But for some reason, I’m highly doubtful that this will work.

Mammoth remains were uncovered in thawed Siberian permafrost, and scientists around the world have been trying to extract DNA from the remains. Previously, paleobiologists were able to reproduce mammoth blood protein, and Japanese researchers want to resurrect the mammoth within five years. This new project will move forward if the Russian institution, the North-Eastern Federal University of the Sakha Republic, can ship its mammoth remains to the Koreans.

The plan would work like previous cloning studies that successfully reproduced dogs, a cow, a cat, a pig, a wolf and coyotes. The nuclei of mammoth somatic cells would be implanted into the nuclei of donor elephant eggs, to produce elephant embryos with mammoth DNA. The embryos would then be implanted in elephant wombs, where they would gestate for 22 months. The team plans to use an Indian elephant for the cell nucleus transfer, according to AFP.

But I guess it’s worth a shot. What can go wrong, right? (Everything.) But how cool would a modern woolly mammoth be?

Aside: The researcher in charge of this project, Hwang Woo-suk, is quite controversial. He previously claimed to have cloned a human embryo and used the clone to generate stem cells. But his methods for obtaining the embryo was later called into question and his results turned out to have been falsified. He served a sentence for embezzlement and bioethics violations for his actions.
