The "Moe Overlord" has been discovered

Ancient discovery: 450 million years ago, this ancient "cute creature" was actually a fierce "catcher" in the ocean

The reporter learned from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences that researchers from the institute, in collaboration with British paleontologists, discovered an ancient arthropod about 450 million years ago in Anji County, Zhejiang Province, my country - the Anji Ancient Horseshoe Crab. The Anji Ancient Horseshoe Crab has a round head and looks very cute. However, it was actually a ferocious carnivore in the ocean at that time, and could be called the "cute overlord" in the ancient ocean.

Wang Han, a doctoral student at the Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, said that the ancient horseshoe crab Anji is a species of the important ancient arthropod Eurycoma. Eurycoma live in fresh water or sea water, and it is more common to live in sea water. The Eurycoma discovered in the past is somewhat similar in shape to the current scorpion, so it is also commonly called a sea scorpion.

The newly discovered Anji ancient horseshoe crab is more round and cute than the various horseshoe crabs discovered in the past. From the fossil, the complete body of the Anji ancient horseshoe crab is about 15 cm long. Its head is rounded, and its trunk is thick in front and thin in the back, divided into multiple sections. Its overall shape is similar to a round mallet. Only the thorn-like tail and the multiple pairs of pincers at the front remind the observer that they were once ferocious carnivores in the ancient ocean.

"The Anji ancient horseshoe crab lived about 450 million years ago and is the oldest eurypodid horseshoe crab discovered in my country so far. Around it, we also found fossils of sponges and other creatures living in the deep sea. These discoveries are of great reference value for understanding and restoring the deep-sea environment at that time, as well as studying the evolution of early arthropods." said Zhang Yuandong, a researcher at the Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, who participated in this study.

The relevant research results were recently published in the international paleontological journal "Journal of Paleontology".
