Studies recover from ancient Squad creatures as early relatives of arrow worms

Notable Jovashim, found in North Greenland, has helped researchers resolve the 500 million -year -old ancient puzzles around ancestors like Squade.

Earlier, it was thought that ancient organisms, called Nikito Cardiades, who resemble squid were a type of saffron. But scientists, who are under the leadership of Bristol University, have now shown that this creature is actually the first offspring of the arrow worms, also known as Chattognatis.

This amazing discovery means that the plain marine arrows were ancestors, with a lot of complex anatomy and a predatory role in food chain.

The study, in partnership with the Korean Polar Research Institute and the University of Copenhagen, is the end of a series of excavation for Series Passet in North Greenland, which began nine years ago. This area is known for the most extraordinary protection of marine biology from early Cambridin, about 518 million years ago.

“Sirius Passet is a treasure trove of jovash,” said Dr. Jacob Winchesar, co -leader author, author at the Macro Evolution at Bristol University. We have not only delicate soft physical fossils but also their digestive system, their muscles and sometimes their nervous system.

“Almost 15 years ago, a research article based on the famous Burgess Shell’s gambling, claimed that Nikito Corridoids were Saifulopads. I never understood it, because it would present everything that we could otherwise know about Cepholopads and you did not know about them.

The enthusiasm of the research team increased when the mysterious Nikito Corridoid’s Jovashim was first standing in the Sirius Paste.

Analyzing 25 Fossil’s samples, researchers succeeded in identifying where the Nikito Corridoids are fitting in the tree of life. This solution comes from the unique conditions of the protection of the Sirius Paste, which in turn results in their nervous system.

Dr. Vinclar explained, “We discovered that our nicoto corridors protect parts of their nervous system as a casting structure, and it was a cheap where these animals sit in the tree of life.”

Recently, the team revealed Jovim in Sirius Paste, another branch of the animal tree.

“These gems preserve a unique feature, which is different for arrow worms, called the Ventral Ganglion,” said Dr. Tai Yun Park, co -leader of the Korean Polar Institute, Dr. Tai Yun Park.

The ventral ganglion is a huge part of the nerve located on the stomach of a living arrow insect, which is unique to this kind of creature. The unique anatomy of the organ, combined with special protection conditions, means that phosphate is replaced by phosphate minerals sometimes.

Dr. Park added, “Now we had a smoking gun to resolve the Nico Corridor controversy. Nikito Corridoids shared numerous features with some other fossils that also belong to the artillery of arrows. Many of these features are like a fish and as soon as they are in awe. “

This discovery helps to reveal the arrow worms and the clusters about their past.

Dr. Vinclar added, “Like our nicoto corridors, the eyes of a complex camera like ours have eyes. Residential arrows can barely make an image where the sun shines. Therefore, the ancestors of the arrow insect were really complex hunters, just as they were produced only 400 million years later.”

“So we can show how food used arrows to capture a character in food chain. Our foes can be much larger than an ordinary residential arrow worm and can be combined with swimming apparatus, eyes and long antenna, they should be strong and stealthy.”

As more evidence of Nico Corridoids swimming, researchers found several samples with the carpets of a swimming arterial in their digestive tract.

The name of Jovasam is Nikitovinths Ausmathi. The names of the species are the first female professor of law in Denmark and the name of Professor Eva Smith, named after the name of the famous human rights advocate.

“My decision to name our foam after Eva after Eva is that this animal was a smart and stealthy fighter, as if it was.”
