What are Trilobites?

Trilobite is the most representative ancient animal that appeared in the Cambrian 560 million years ago. It is a kind of arthropod. The whole body is clearly divided into three parts: head, chest and tail. The two dorsal furrows are longitudinally divided into approximately equal three pieces-one axe and two ribs, hence the name trilobite.

In taxonomy, trilobites belong to

After years of research by paleontologists from various countries, it is believed that trilobites have complex developmental stages

After the appearance of the trilobite, throughout the Early Paleozoic (including

On April 15, 1958, China issued a set of "

Trilobite is also the name of a kind of "tribute tea" in China-

Strange palaeofossils suspected of trilobites found in Liyang, Chongqing (1/8) [4]

On September 18, the author found some strange insect fossils in Maoba Village, Maoba Town, Liyang Tujia and Miao Autonomous County, Chongqing. Several local villagers took a look at the fossils at the scene. Chen Bisheng / Dongfang IC

The outline of unknown ancient creatures about 7 cm long and 3 cm wide is clearly visible.

The biggest feature of these fossils is that the feathery "tentacles" are lifelike.

According to some elderly people, this is called a trilobite fossil, which is estimated to be hundreds of millions of years ago.

Fossils are found on such rocks.

The lines left by the insects are clearly visible.

Strange fossils found by local villagers. Palaeontological fossils are non-renewable geological natural heritages left over from the normal geological history of the earth's evolution. They have great reference value for studying geology, geology, and climate. Liyang is located in the hinterland of Wuling Mountain, and is rich in paleontological fossil resources. At present, the author informed the local government of this situation, and the other party stated that he would send someone to conduct a site inspection on this.

Trilobite is the most representative ancient animal that appeared in the Cambrian 560 million years ago, and reached its peak from 500 million to 430 million years ago. The Permian was completely extinct 240 million years ago. Living on the earth for more than 320 million years, it is a class of highly-living creatures. Over a long period of time, they evolved into a variety of species, some as long as 70 centimeters and some as small as 2 millimeters. The carapace is a trilobite, which is divided into two axe leaves and two rib leaves longitudinally. (Information map) ^[3]
