According to a latest report, Nora Noffke of Old Dominion University in the US has discovered the remains of, what once was a purple-and-green slimy, smelly mat of single-cell microbes.

These microbes are assumed to have worked, lived and even communicated with each other at that time.

According to sources, these findings by the researchers are assumed to be the oldest complete fossil on earth. The researchers say that these old fossils paint a smelly but colorful picture of our microbial ancestors.

The sources have also revealed that these findings suggest that these microbes existed about 3.5 billion years ago. These fossils of microbes suggest that these creatures survived in a proper prehistoric microscopic society.

According to sources, these findings were discovered by Nora Noffke in sandstone rock in Western Australia. The researchers have come to this conclusion, after studying these microbial findings, that these microbes could have been our ancestors.

Study co-author Robert Hazen, who is a mineralogist at the Carnegie Institution of Science in Washington says that this miniature fossilized mat, which is about 8.3 millimeters thick, would be about 300 million years old and is still a debatable topic.

Hazen said, "If you had walked the Australian beaches of 3.5 billion years ago, you would see this slimy mass of purple or brown fibers emitting this stench of sulfur compounds but living very happily".
