East China was a creature 200 million years ago?Expert: There is also Chengdu, more old than dinosaurs

Cover journalist Zeng Jie intern Lin Xiaotu provided by the respondent

"Jurassic World 3" uses special effects and feelings to satisfy people's imagination of dinosaurs and grab a box office of 1 billion yuan. Another compartment, commonly known as "three -eyed dinosaur", may be based on "dinosaurs". The halo is hot search, causing hot discussions on the entire network.

On July 21, the topic of "community ponds discovered 200 million years ago" related topics, the hot search was hot, and the reading volume exceeded 150 million. Mr. Song, a citizen of Donghai County, Lianyungang, accidentally found a creature with three eyes and shrimp -like creatures in the pond of the community. It is confirmed by experts that this is a "tapeworm", commonly known as "three -eyed dinott", and is an old -fashioned species that is older than dinosaurs.

What kind of creature is a tapeworm? Why are dinosaurs who are still alive? Cover news reporter interviewed Zhao Li, the curator of the Chengdu Huaxi Insect Museum. He posted a few photos of the tapeworms and collected fossils he took. The appearance has almost no change in the appearance of millions of years. You see the pictures I sent to you. Compared with the fossils of 165 million years ago, the photos taken on the scene are almost consistent, just a little smaller. "

Earn earlier than dinosaurs

Activated stone without folding

Director Zhao Lizang introduced that tapeworms, alias three -eyed dinott, are a small type of crustacean, belong to gill footnets, back nails, 15 species in the world, inhabited in lakes or ponds. One is called Jiapeng Terrace. The tapeworm has a circular back armor and long tail. It looks like marine animals, but unlike the cricket, it can only live in the freshwater environment.

In the world, ticks are mainly distributed in Europe and North America. my country is more common in Gansu, Inner Mongolia and Northeast China. It was first discovered in Chengdu in 2014.

Terraper is regarded as one of the oldest creatures on the planet. Zhao Li said with a smile that these two creatures have no blood relationship. Before that, people mistakenly thought that tapeworms and dinosaurs appeared at the same time, so they were called "three -eyed dinott", and the latest research results showed that as early as 300 million years ago The paleontic carbon period has appeared, and it is earlier than the dinosaurs.

Open the search engine and enter the first entry pop -up of the tapeworm is "Can I eat it." Since coexisting with dinosaurs, can ticks may become a dinosaur's beauty meal? Zhao Li revealed that when the tapeworm appeared in Inner Mongolia, it was used by the people to feed chickens and ducks. At present, there is no evidence to show that dinosaurs prey for tapeworms, but he speculates that some small pterosaurs are likely to capture when fishing. The tapeworm in the water may be a meal.

Chengdu has discovered

Come and have no shadow

Zhao Li was very familiar with the tapeworm. He recognized at a glance that the tapeworm in the above news was found in Chengdu.

At the end of May 2014, he received a phone call. Someone found a strange creature in a paddy field in Pengzhou, Chengdu. He immediately rushed to the scene and saw this kind of creature with three eyes. A long tail, the abdomen is exposed outside the back armor, and there is a pair of soft tail beards at the end of the abdomen. The locals have never seen these strange creatures, and they feel strange. Zhao Li recognized that this was an ancient biology tapestorm. Because he was found in Chengdu for the first time, he was very excited. He took many photos and made specimens.

It is worth mentioning that tapeworms suddenly appear in the special fields of Pengzhou at the end of May each year without appearing in other waters. At the beginning of June, the tapeworm disappeared without a trace, which was called "the ghost out of ghosts."

Why does the tapeworm appear seasonal? Why only appear in this paddy field? Documentary teams came to shoot, and there were still no reasons for the investigation. Zhao Li speculated that they may be more sensitive to the environment.

After a year, a friend who was engaged in paleontology research inspected Inner Mongolia, and discovered a tick fossil that was 165 million years ago, presented it to Zhao Li, and was displayed in the museum. He got the fossil and compared it carefully with the specimen he made. The tapeworm in the fossil was slightly larger, about 9 cm long, and the existing tapeworm specimen was only 6 cm long.

"Except for slightly bigger, the appearance characteristics are almost consistent." He was surprised by this, 165 million years, and the appearance of these tapeworms has almost no change, maintaining the primitive appearance. Due to the slow evolution, some people call it "the dull group of evolution", "Darwin once believed that this classmate did not compete in the survival process."

Vitality is tenacious than dinosaurs

Eggs can survive for 20 years

The fossil data proves that the earlier generations of carbon -generation charcoal that first appeared 300 million years ago was about 70 million years earlier than the Dinosaur who appeared in the Middle -generation. After many years, people can only use movies such as Jurassic World to satisfy their curiosity about dinosaurs, but the older tapeworms are survived to this day. No matter the vicissitudes of the sea, water can reproduce.

The popular science blogger "Museum Magazine" with more than 12 million fans has been asked by netizens many times and asked to identify tapeworms. There is no difference between the ancestors of the dinosaur era. It is considered to be a living creature. This thing often appears in temporary water bodies such as paddy fields and after the rain, because their eggs can sleep in drought for many years. After distribution, after spawning, the water body is dried up, adults die, and eggs continue to sleep. "Terraper appeared in Chengdu for the first time in 2014

The ability to adapt is quite strong -this is also Zhao Li's comment on tapeworms. He further explained that although adults generally have only one or two months of life, the eggs may survive in drought, cold, and high temperatures for two or three decades, or even longer, until the moment of the water arrives. This is why they can escape the extinction of Bai Yan's dinosaurs, and they are prosperous again after the glaciers.

What if people accidentally come with such ancient creatures? Although the "Museum Magazine" stamping tapeworm is non -toxic, although this creature is not a national -level protected animal, Zhao Li also suggested that people "do not fish", but look at it from a distance and not to play. After all, this is the best activated stone to witness the dinosaur era. Essence
