Nanjing on November 3030 learned from Nanjing Institute of Geology and paleontology, Chinese Academy of Sciences, that the Cambrian explosion research team recently discovered a strange insect about 500 million years ago in Weifang, Shandong Province. The head of this ancient insect is shaped like a pair of rabbit ears. Scientists named it “ear shaped fantesier”. According to the introduction, the new species is a kind of trilobite. In the Cambrian period 500 million years ago, trilobites were worthy of the title of “sea overlord”. Their body surface has a strong carapace, like a warrior in armor. From 520 million years ago to 250 million years ago, trilobites lived on the earth for about 270 million years, showing the tenacity of life. The newly discovered species is about 4cm long and has a peculiar appearance. Its head is long and narrow, nearly half the length of its body. The front side of the head shell extends forward on both sides, and there is an obvious notch in the middle, which makes it look like a pair of rabbit ears. < / P > < p > “this is the first time we have seen such a strange looking insect. They grow such strange heads, may be to confuse natural enemies, or may be out of the need for predation Zhao Fangchen, a researcher at the Nanjing Institute of Geology and paleontology, Chinese Academy of Sciences, who led the study.
