According to the Siberian Times, scientists analyzed over 300 prehistoric worms and found that two nematodes discovered in different areas of Siberia still showed signs of life after being trapped in ice for 42,000 years.

Scientists have made a discovery that is quite mind-blowing.
Another was found in permafrost near Alazeya River in 2015, and is around 41,700 years old. They were stored in petri dishes at -20 degrees Celsius in a lab before being "thawed" over the course of several weeks. After defrosting the worms, the researchers saw them moving and eating, making this the first evidence of "natural cryopreservation" of multicellular animals, according to the study. That marks the first documented time multi-cellular organisms have returned to functioning after being frozen in permafrost.

To be fair, nematodes or roundworms have always been hailed as a beast in survival. Similarly, tardigrades that had been frozen for 30 years were brought back to life by Japanese researchers in 2016, as Gizmodo pointed out.
Both samples came from the cold Yakutia region in Russian Federation, but one came from a permafrost wall in a squirrel burrow, while the other was found in permafrost near the Alazeya river way back in 2015. Now, imagine getting a wake-up call after being "asleep" for 42,000 years.
The scientists said they can't rule out the possibility that the samples were contaminated at some more recent point, but said they kept the experiment as sterile as possible.
Folks on social media were both excited by and a bit apprehensive about the frozen worms being revived.
Though nematodes are tiny - typically measuring about 1 millimeter in length - they are known to possess impressive abilities. They've been found living nearly a mile below the Earth's surface, and some have even adapted to living inside slug intestines, according to Live Science.
