The samples of Volyn biota were found in samples from miarolitic pegmatites ("chamber pegmatites") collected from the of the
Ukrainian Shield. They were described as early as in 1987, but interpreted as abiogenic formations. Until very recently the origin of the Korosten pegmatites was not fully understood, but they were dated to 1.8-1.7 Ga. Franz et al. (2022, 2023), investigating newly recovered samples they date to 1.5 Ga, described the morphology and the internal structure of Volyn biota and reported the presence of different types of filaments, of varying diameters, shapes and branching in the studied organisms, and provided evidence of the presence of
fungi-like organisms and
Precambrian continental
deep biosphere. Some fossils give evidence of
sessility, while others of free-living lifestyle. ==See also==
