Polopark polycarpon age of 100 million years, found in amber Source:

Fossils of ancient insects regularly find in amber. The inclusions allow scientists to study the past of our planet and how, over time, evolved a variety of species. So, during the excavation of amber in Myanmar (Southeast Asia) was found bizarre creature, older than 100 million years, which looks similar as the Scorpion, and so on . During the excavation of two independent groups of researchers found four copies with the arachnids, which, as the researchers believe, will help scientists fill in the gaps in the understanding of the evolution of spiders. The paper was published in the journal .

How did the Arachnida?

Arachnids or Arachnida are a class of arthropods. The researchers described no less than 114 thousand species. The most famous representatives are the spiders, Scorpions and . However, only the spiders are famous for the availability of dies — parts of the limbs that help them to produce the web. Given that spiders live on our planet about 300 million years, they had enough time to find its niche in the animal world. So, over time male spiders have got a smooth back, unlike the Scorpions, with their segmented backs, which they inherited from their ancestors who lived on Earth 450 million years ago. Discovered in Myanmar fossil illustrates the evolution of the arachnids — a creature in amber can be called a Chimera: head of a spider, but the end of the body just like the Scorpion, only with more legs. Like a Scorpion, fossil have long, whip-like tail. However, the researchers believe that the tail of an ancient arachnid running away and more like antenna.

What relatives of the arachnids found the scientists?

In 1989, scientists discovered an ancient fossil, which clearly exceeds the age of modern spiders. Only in 2008, paleontologists found out that this spider was not the real spider, and his distant relative. The finding was attributed to the category of Uraraneida — an extinct species of spiders, which, as the researchers believe, lived on Earth 400-250 million years ago.

Ancient insects are often found inside amber

The Study Uraraneida stuck in , worked on two independent research groups. In the result, both teams came to the conclusion that trapped in the petrified resin of the entities belong to different genus of arachnids. A few images of the obtained samples, you can see the top and bottom of the body of arachnids. The degree of fossilization provided the transparency when viewing that allowed researchers easier to identify the anatomy of the spider.

The Most striking difference between the findings from modern spiders is the presence of long segmented tail like a Scorpion. This has led many researchers to the conclusion that the ancients possessed inherent traits. In addition, the age of the amber, which stuck these creatures is about 100 million years.
