In 2023, it was reported that nematodes of the previously undescribed Panagrolaimus kolymaensis were revived after 46,000 years in cryptobiosis. [2] [3] However, a number of scientists expressed skepticism regarding the accuracy of the age analysis for these worms. [1] Phylogenetic analysis and genome comparison with C. elegans revealed that ...

Various claims have been made about reviving bacterial spores to active metabolism after millions of years of dormancy. Spores preserved in amber have been revived after 40 million years, [10] and spores from salt deposits in New Mexico have been revived after 250 million years, making these bacteria by far the longest-living organisms ever ...
Between 1963 and 1991, archaeologists discovered Judean date seeds in excavation sites. Through radiocarbon dating, they were determined to be between 1,900 and 2,300 years old. In 2008, researchers at the Arava Institute for Environmental Studies began to germinate the seeds. [2] As of 2023, 7 Judean date palms have successfully germinated. In ...
Sometimes we get lucky—like a team did recently, when they located a fossil of a 520-million-year-old worm larva that still had its brain and guts intact.
