Amber freezes insects, a pair of loving flies are trapped, and maintain a”fit” posture for 41 million years

Speaking of amber, I believe many friends know that this is a kind of transparent biological fossil. When the resins of conifers, yunaceae, and Araucariaceae drip, these resins will form a kind of amber fossils after a long period of time under high temperature and high pressure. Since our common amber is mainly formed from the resin of pinaceae, amber is also known as”fossil fossil”.

Although the main components of amber are the resins of these plants, Inside, there may be some unexpected objects. When these resins drip from the tree, if there are just some small insects under them, these small insects may be surrounded by these resins, and”fixed” by the resin, and finally become fossils with these resins. In general, these amber fossils have a long history, and some may be as long as tens of millions of years.

Scientists have discovered some amber up to 99 million years h3>

According to a scientific report published in the Proceedings of the Royal Society B:Biological Science on July 1, 2020, scientists have discovered some ancient amber, and the insects in the amber have been frozen for 99 million years. Although it seems very long ago, these insects still maintain bright colors. For these small insects and other organisms, the life span is limited. When these organisms die, they will be quickly decomposed by microorganisms, but when these organisms are trapped in some resins, they may become amber together with these resins. Fossils can be preserved for a long time.

In this study, the researchers collected 35 amber specimens containing ancient insects In these samples, most insects are some wasps, such as”Cuckoo Hornets” and so on. Although it has a history of 99 million years, these”cuckoo wasps” fixed in amber still maintain almost the same color as the current cuckoo wasps.

Since these resins are dripping, there are no signs, and some insects under the resin may not perceive that these resins will affect them. In addition, when these insects encounter resin, their forms are different, so they will be trapped in the resin in various postures, and eventually become some”shaped” fossils. Researchers had previously discovered a piece of amber, and within the amber were a pair of loving flies. They have given their lives for love, maintaining a”fit” posture for 41 million years.

Although the pair of flies have been trapped for 41 million years, their remains are still relatively good, and their legs, feet, wings and other limbs remain Very well. This is because these resins trap these insects, and these insects are”isolated from the world” and generally not destroyed. After a long period of time, these insects and resin perfectly merged into amber fossils. From the photos, we can see that the flies are still perfectly combined, but they seem to have a tendency to separate. It may be that after the flies were trapped by the resin, they tried to escape from the danger and ended in failure.

For this pair of flies, although they died shortly after being trapped, they are now permanently preserved, unlike other ones Organisms are quickly decomposed by microorganisms after death. The discovery of these ambers provides us with some good research specimens for studying the evolutionary course of the earth’s biology. Because we can’t go back to a long time ago to study these prehistoric creatures, generally we can only understand the evolutionary process of biology by studying fossils and other methods. The insects in these ambers are well-preserved, allowing us to directly see what the creatures looked like in the distant past.
