Four of these species were from the pandoravirus, cedratvirus (sometimes classified as a subgroup of pithovirus), megavirus and pacmanvirus (part of Asfarviridae) families, which weren't previously revived from the permafrost. In addition, five more species from these families were found in already thawed permafrost, with no way to tell their age.
The constant presence of permafrost is able to preserve the soft tissues of organisms through a process similar to freeze-drying. [1] With such complete preservation of tissues, it is possible to determine numerous things from the such as: DNA, eDNA, [ 2 ] evolutionary history, [ 3 ] gut contents, [ 4 ] and trophic dynamics.

For the past 24,000 years, the multicellular microorganism had been snoozing in Siberian permafrost, having become frozen in the Arctic ice right around the same time in history that humans first ...
Researchers in Russia on Monday unveiled the remarkably well-preserved remains of a 50,000-year-old female baby mammoth found in thawing permafrost in the Yakutia region of Siberia.
Remains attributed to the species display a considerable range of morphological variability. [9] The species had a small body size, with adult individuals estimated to have a body mass of around 300–365 kilograms (661–805 lb), [3] with the mummy of an 8 year old adult male horse (the Selerikan mummy) having a height of 1.35 metres (4 ft 5 in) at the withers.
Researchers in Siberia are conducting tests on a juvenile mammoth whose remarkably well-preserved remains were discovered in thawing permafrost after more than 50,000 years. The carcass, weighing ...
A study of Brazilian Ediacaran fossils found filamentous microfossils, suggested to be eukaryotes or large sulfur-oxidizing-bacteria (SOBs). [81] Fungus-like filaments found in the Doushantuo Formation have been interpreted as eukaryotes and possibly fungi, providing possible evidence for the evolution and terrestrialization of fungi ~635 Ma. [82]
In Russia's far northeastern Yakutia region, local scientists are performing an autopsy on a wolf frozen in permafrost for around 44,000 years, a find they said was the first of its kind. Found by ...
