On November 9th, an amber wrapped in 22 million-year-old aquatic shrimp specimens was unveiled. The discovery team said aquatic life preserved in amber is rare, and this “amber shrimp” provides scientists with clues as to how aquatic life is transitioning from the marine environment to a freshwater environment. There have been no international reports of the discovery of real shrimp amber fossils.
A team of researchers from the Institute of Zoology of the Chinese Academy of Sciences, Nankai University and the Institute of Oceanography of the Chinese Academy of Sciences found the shrimp specimen. The amber, which originated in the Central American region of Mexico and formed in the early Mesozoic period about 22 million years ago, provides valuable evidence for understanding the ecosystemand and biodiversity of the Gulf of Mexico at that time, said Dr. Chen Rui of the Institute of Animal Sciences of the Chinese Academy of Sciences.
Chinese scientists have “identified” the amber. Li Xinzheng, a researcher at the Institute of Oceanography of the Chinese Academy of Sciences, said that the specimen is in good condition, the morphological features are clearly visible, and the overall appearance is very similar to that of the current growing arm shrimp species, indicating that the shrimp perched in the estuary environment, slender and free to live, belonging to the long-arm shrimp sub-family, long-arm shrimp genus.
David Huang, a professor at Nankai University, said that “amber shrimp” is the oldest real shrimp found on the chest armor with nail trench and nail gills, which can help to study the adaptive evolution of real shrimp species and provide clues for the study of the transition of aquatic life from the marine environment to the freshwater environment.
The amber is currently kept in the Stone Museum of Zhongguancun Library building in Beijing and is open to the public. The research paper was published recently in The Scientific Report, an academic journal of nature publishing group.
