It’s not often you get chance to look at something that’s several billion years old – we’re totally amazed by these fossilised remains, found in rocks formed from microbial mats that settled in shallow pools some 1.6 billion years go.
The holes you see were formed by oxygen bubbles given off by tiny microbes, setting the foundations for life as our planet started to become increasingly hospitable.
That’s according to a new study on the mats carried out by researchers in Sweden and Denmark, who describe their findings as “a signature for life”. The billion-year-old material can teach us more about this distant period of history, say the researchers.
