Pigments are extracted from the flakes of the Black Sea of the Taoudeni Basin in Mauritania, Africa
REPUBLIKA.CO.ID, JAKARTA – Scientists find the oldest color in the geological record. The color predicted at 1.1 billion years is a bright pink pigment. This color is extracted from the rocks below the Sahara Desert in Africa.
Pigments extracted from black sea flakes from the Taoudeni Basin in Mauritania, West Africa. The discovery of this color is older than half a billion years than that of the ancient discovery of pigments
"The bright pink pigment is a molecular fossil chlorophyll produced by an ancient photosynthetic organism that inhabits an ancient sea. has long since disappeared, "said a researcher from the Australian National University (ANU) Nur Gueneli, quoted by Financialexpress.com

published in the journal PNAS this fossil color is between blood red to dark purple in concentrated form, as well as bright pink when it is dissolved . The researchers destroyed the stones one billion years ago in powder, before extracting and badyzing the molecules of the ancient stone organisms.
The badysis of ancient pigments confirms that small cyanobacteria dominate the food web in the ocean. a billion years ago. This explains why animals did not exist at the time.
"The emergence of large active organisms tends to be limited by the limited intake of larger food particles, such as algae," says Jochen Brocks, chief research officer
. time greater than cyanobacteria . The algae cyanobacteria began to disappear about 650 million years ago, when algae began to spread rapidly to provide the energy necessary for the evolution of ecosystems complexes, in which large animals, including humans, can thrive on Earth, "he said.
