Scientists discover strange "shrimps" 500 million years ago

Xinhua News Agency, Nanjing, September 1 (Reporter Wang Wei) reporters from China
Nanjing Institute of Geology and Paleontology was informed that the institute's researchers recently found a 500 million-year-old primitive arthropod in Linyi, Shandong Province: line-printed shrimp. This line-print heart shrimp, is a Cambrill star animal strange shrimp, they have a loving head, in the ancient ocean to hunt.
in the Camsoon ocean, the odd shrimp is the most ferocious predator. They are large and strangely shaped, with fore limbs and long tails that can be hunted quickly. The largest odd shrimp individuals can grow to more than 2 meters, while most other animals at that time were only a few millimeters to a few centimeters. Coupled with their hard shell, these Big Mac animals are almost king of the sea. However, although the name, look and shrimp are similar, the odd shrimp and modern shrimp are not related. They are a large group of extinct primitive arthropods.
, the research team found in Shandong, China, the line-print heart shrimp, is a relatively "mini" strange shrimp. It is about 30 cm long and the front of the body is covered by a huge heart-shaped head shell, which is almost half the length of the body. In the notch at the back of the head shell, a pair of large eyes are protruding. Beneath the head shell is a ringed mouth consisting of four large teeth and many small teeth, and a pair of special claws located in front of the mouth. The pair have blade-shaped blades on their paws, which also have dense long thorns. This complex claw structure may be used to shake sieve sediments or seawater for predation.
" compared to the other 1 meter or more of the big strange shrimp, line-print heart shrimp seems to be a 'little cute': small claws, small mouth, but also grow a 'love head'. Qi shrimp is one of the most representative star animals of the Cammason life outbreak, this time found in Shandong Province, foreshadowing that there are still more Camdhan fossils in China, for people to explore the mystery of the origin of life. Zhao Fangchen, a researcher
Nangu Institute who led the study, said.
results have been published in the international geological journal Sangu.
