Scientists have found living creatures possibly 830 million years old trapped in an ancient rock, which was described as an amazing discovery that may reveal a new form of life on ancient Earth.
A team of geologists have discovered tiny remnants of prokaryotic life and algae, trapped inside halite crystals dating back 830 million years.
Halite is sodium chloride, also known as rock salt, and this discovery indicates that this natural substance could be a previously untapped resource for studying ancient saltwater environments.
The exciting thing is that these creatures are still alive, trapped inside the rock. The unusual study, published in the journal "pubs", also has implications for the search for ancient life, not only on Earth, but in extraterrestrial environments, such as Mars, where large salt deposits have been identified as evidence of ancient and extensive liquid water reservoirs.
According to the article published in the scientific journal "Sciencealert", when crystals form in a saltwater environment, small amounts of liquid can be trapped inside. These are called fluid impurities, and are the remains of the mother water from which the halite crystallized.
These crystal stones are of scientific value, because they can contain information about the temperature of the water, the chemistry of the water, and even the temperature of the atmosphere at the time the mineral was formed. Scientists also found microorganisms living in these environments, where halite forms a highly saline environment, however, microorganisms such as bacteria, fungi and algae were found thriving in them, some modern and some dating back to ancient times. However, the method of identifying these ancient creatures left some doubt as to whether they were the same age as halite.
A team led by geologist Sarah Schrader Gomez of West Virginia University used ultraviolet lithography and transmitted light, and when magnified images up to 2,000 times to study fluid impurities in them, the researchers found organic fluids, compatible with prokaryotic and eukaryotic cells, based on their size and shape. Ultraviolet flash.Some samples showed colors consistent with organic decomposition, while others showed the same fluorescence of modern organisms, suggesting, the researchers said, unchanged organic materials.
The researchers pointed out that it is possible that some organisms are still alive. The fluid contents could serve as micro-habitats where small colonies of these organisms thrive. Live prokaryotes have been extracted from halite dating back 250 million years, so it may be possible for these organisms to date back about 830 million years.
