The thing about fossils is that they are older, these rarer. Earth does not hide anything around forever, and the more you go back in time you are more likely to find evidence of plants and animals then. So, when we mention about the fossils of the creatures who died over 500 million years ago, you can imagine how much they can find, but paleontologists in China just enter a mother's code.
A new researcher paper published in Science details the discovery of literally thousands of primitive specimens in ancient hard sediment on a river in China. The site, called Qingjiang, is full of evidence of the bodies of soft bodies that, until now, have gone up to the hour.
Fossils of animal bodies have been found to be hard to find because the soft tissues are wobbly fossilized. On the other hand, shells and bones have a better shot than standing in the test of time, so the discovery of a wealth of soft creatures is a really great thing for paleontologists.
As National Geographic explains, the thousands of specimens observed have been identified as 1
Fossils are left in ancient sea creatures living in the sea at death, covered with mud and dregs and gradually become compressed with stone mortar. Now, as scientists flake the stones away they can see the ghostly shadows of fossilized tissue that make up their bodies, such as a window by time.
Creatures are some of the earliest complex forms of life on Earth, which appeared during the Cambrian Period where Earth life began to branch in different forms quickly. Scientists do not get the chance to find dozens of new species simultaneously, so this is a rare treat.
