Scientists have managed to reanimate worms that were frozen for an estimated 46,000 years.
Thought to have lived in the late Pleistocene era, a small group of the worms found 40 metres deep in the Siberian permafrost have been thawed out and revived.
The worms are from the long-extinct species Panagarolaimus kolymaensis and were not actually dead, but in a dormant state known as cryptobiosis which renders their vital signs undetectable.
Scientists previously only had evidence nematodes or roundworms were able to remain in this state for up to 40 years, but these creatures coexisted with woolly mammoths.
Professor Teymuras Kurzchalia, senior author of a study of the worms, published in the journal of PLOS Genetics, and emeritus professor at the Max Planck Institute of Molecular Cell Biology and Genetics in Germany, said: “This little worm could now be in line for a Guinness World Record, having remained in a state of suspended animation for far longer than anyone thought was possible.
