So why can this heart be preserved for 380 million years?
In fact, this heart can be preserved for 380 million years, mainly under certain circumstances, or it may be a coincidence. Because the evolution of fossils really needs to be in a specific environment, then they will be isolated from oxygen and will not rot, so they will be well preserved. For example, the temperature was dry at that time, or the fish was buried under mud, so it was very likely to be preserved. So the specific reason is still unknown, but we have to admit that this is the most complete heart left, and it can also be modeled in 3D, which really helps scientists to study.
How rare is this heart?
In fact, fossils are not particularly rare. The fossils found before are all flat, but this time the heart can study three-dimensional patterns, which can be said to be the first time, so it is very rare. Moreover, with the help of modern scanning technology, we can carry out research and observation without destroying fragile soft tissues, and this series of operations can provide researchers with a good foundation for human evolution. Although there are many fossils now, the soft tissues of ancient species are rarely preserved, especially in 3D. Therefore, this is a great discovery, and it is also very shocking.
