400 million-year-old fossils found in the sophomore boy community are rare in Fuzhou

The fossil of Amenjiao stone found by Kobayashi is large

Fuzhou Evening News, September 17 (Reporter Chen Danwen / Photo) The sophomore boy went home for the Mid-Autumn Festival on vacation and saw an abandoned piece of marble on the grass of the community, which was wrapped in animal fossils from more than 400 million years ago - AmenJiao Stone. This unexpected Mid-Autumn Festival "gift" made Lin Xianghong overjoyed.

Marble base

The pattern is very special

Lin Xianghong's family lives in Cangshan Fuwan New Town, this year's second year of college, due to the typhoon school holidays in advance, on the 14th at 14 o'clock to return home. As he carried his luggage through a meadow downstairs in the neighborhood, he was attracted by a piece of round cake marble. Kobayashi is a fossil "enthusiast", usually walking always like to stare at the stones on the ground, out of habit, he casually turned over this piece of abandoned marble, but was surprised to find that there is a large section of special pattern in the stone.

Although he majored in digital media, Kobayashi liked to collect paleontological information since he was a child, and also joined the fossil forum and held a fossil exhibition at the school, and he recognized at a glance that this special pattern was actually a fossil, and it was a menjiao stone. Kobayashi looked closely and found that there was a nut nut nut in the middle of the stone, which was exactly the same as the base of the coat rack at home. It is estimated that the clothes and hat racks of the family were broken, and the base was casually thrown in the grass.

Such a complete fossil

Rare in Fuzhou

"I didn't expect to be able to pick up fossils when I came home in the Mid-Autumn Festival!" Kobayashi took a photo of the fossils he had picked up and sent them to familiar paleontologists and fossil enthusiasts, who all thought it was a fossil and called it a Mid-Autumn Festival "welfare".

Yesterday, the reporter saw in Kobayashi's home that this marble is no different from ordinary stone, but there is a white pattern similar to the wheel print inside.

Kobayashi told reporters that Amen horn stone is an ancient invertebrate that lived in the Ordovician period more than 400 million years ago and is now extinct. It is a close relative of the modern Nautilus and one of the most common fossils of the Ordovician strata, commonly found in a variety of limestone architectural stones.

"It is speculated that this fossil comes from the Ordovician strata in the northern region of China, and the cross-section is well preserved, the biological structures such as the body tube and partition of the hornstone are clearly preserved, the shell is all decontaminated and petrified, and the fossil specimen is 23 centimeters long." Kobayashi believes that the origin of this fossil was an ocean more than 400 million years ago.

It is understood that it is not illegal for citizens to excavate ordinary fossil specimens such as trilobites and cephalopod fossils, but if they sell a large number of fossils privately for profit, they will violate relevant laws and regulations. Kobayashi said that this fossil cannot be bought and sold, and has a high scientific value. "Such a big one, I saw it for the first time in Fuzhou, and the general corner stone is only exposed by about 5 centimeters." Kobayashi said he had found fossils in many parts of Fuzhou, such as the old campus of Fukuda University, West Lake Park and other places where he found fossils hidden in stones.

For the fossil that Kobayashi picked up, a teacher of paleontological stratigraphy at China University of Geosciences said that it was indeed a Mallangite from the Ordovician, produced in marine limestone (that is, the black marble). The cross-section of this hornstone fossil is large and complete, and you can clearly see the link beads and the inner tube, and the structure is clearly layered, which is a good popular science specimen.
