Now everyone who is interested in arachnids, an opportunity to look for the first time in 49 million years in the face of the most ancient spider. Through the use of high-tech X-ray methods scientists were able to penetrate the veil of amber enveloping fossil spider to see him up close.
Post, published online in the journal "Naturwissenschaften", confirms that the ancient spider is a member of the genus Eusparassus. These arachnids, also known as spiders hunters live in the tropics, as well as in Southern Europe today. In width, they can reach nearly a foot (0.3 meters). Hunters spiders are not aggressive and are not poisonous, but they can leave painful bites.
One of the most terrifying parts of the body Spider Hunter are his fangs shown closed at this ancient arachnid. Ancient fossil spider, which is located in the Historical Museum of Nature in Berlin, buried in a darkened piece of amber, and you can barely see. Using a method called X-ray computed tomography, researchers from Germany and the United Kingdom have created a three-dimensional image and video spider in amber.
The resulting X-ray images show the teeth, the eyes and the "tentacles" or mustache on the face of a spider. The same method was used to show other fossil spiders. This CT scan shows the head fossil hunter spider that lived about 50 million years ago.
That was around when this giant arachnid crawl there, what is now central Europe? Another giant, as recently reported by the researchers was the ant-sized hummingbird, who lived in an area now referred to as the State of Wyoming, USA. Ancient fossil hunter was found in the 1800s.
Naturalists then suspected that it was not a hunter, but modern scholars seem rather strange that such a large, active spider stuck in the resin of the tree. When compared to other fossil specimen and modern spiders, however, they could only determine that fossil hunter really is.
"The study is particularly exciting because our results show that this method works and that other samples are important from a scientific point of view, which are historical pieces of darkened amber can be investigated as well as their existing family" - said in a statement David Penny (David Penney), a researcher from the University of Manchester.
