Scientists have detected traces of unusual organisms the age of 2.5 billion years. They probably belong to the cyanobacteria, but have a very large size and unusual shapes. This publication reports Live Science.

Tiny fossils (microfossils) belonged to creatures that lived 100-200 million years before the oxygen disaster is a relatively sudden and global changes to the composition of Earth’s atmosphere, which oxygen. The great oxidation event occurred about 2.45 billion years ago. Until now, researchers have described only four cases of finding microfossils dated to that time period.

Currently, the size of the majority of cyanobacteria reaches 5-10 micrometers, and the largest grow to 60 micrometers. However, some of the organisms found up to 100 micrometers in diameter. In addition, individual cells have strange protrusions that could arise from “budding” (asexual reproduction). Currently, cyanobacteria are not kidney, so scientists can’t exactly determine the nature of these processes.
