After gathering and analyzing over 300 samples of permafrost deposits, the crew discovered that two of them contained viable specimens of soil nematodes (worms). One of those samples was taken from a floor squirrel burrow within the Duvanny Yar outcrop, which has beforehand been radiocarbon dated to about 32,000 years. The second pattern was a drilled ice core from a glacial deposit close to the Alazeya River, which corresponds to round 41,700 years of age.
