Ancient Earth as we know must have been a place unimaginable for us humans. Currently, it’s all beautiful with lovely green canopies and deep blue but would you imagine cliff jumping into oceans stained pinks and purples? Researchers discover that’s what earth looked like back in the day!
This is also the Earth’s oldest colour. Researchers discovered the pink pigments from fossils of cyanobacteria excavated from the Sahara desert in Mauritania, west Africa. It’s assumed that cyanobacteria survived on sunlight and were a dominant life on Earth untill 650 million years ago.
The study published in the journal of the national academy of sciences reveals that chlorophyll present in them wasn’t the luscious green we popularly know today but was rather dark red and purple in it’s concentrated form. When mixed with soil or water it releases a pinkish hue.
Although a rare fossil, it is believed that these cyanobacteria were formed due to a bloom sinking below to the ocean floor where oxygen couldn’t reach and thus prevent their decay. Over time, the bloom fossilized and the rock remained unshaken for many years to come.
Thia means that along with unbearable temperatures, Earth resembled a sphere of cotton candy, which wouldn’t be too enjoyable to eat.
