A team of paleontologists from China, Estonia, the United States and the United Kingdom, using the latest microscopic imaging technology, captured the breeding moment of chitin, a tiny animal that has lived in the ancient ocean for more than 100 million years. Chitins are very small organisms. They live in the ancient ocean 480-360 million years ago. Their body length is measured in microns. In terms of shape, they have various shapes, such as long necked bottles, pots, cylinders and so on, like miniature “floating bottles”. Although small, chitins can help human find mineral resources such as oil, and provide important clues for scientists to solve the mystery of mass extinction. However, its biological properties have been poorly understood. < / P > < p > this time, the scientific research team used a number of high-end technologies such as near-infrared microscopic imaging and micro CT to study a batch of fossil chitinas 460 million years ago. Researchers have discovered unexpectedly that a special chitin specimen, which has long been regarded as abnormal variation, is actually the key material for recording the reproductive moment of chitin. By looking at 20 of these special specimens, the team identified two reproductive patterns of chitins: one mother reproduces one offspring at a time, or more than one offspring at a time. < / P > < p > the team also restored the reproduction process of the chitin beetle: the bottom of the mother became thicker, and then the bottom of the offspring grew out here. At the same time, the neck of the offspring chitin also develops in the mother. After the development of the two, they will be integrated and separated from the mother. This is typical of asexual reproduction. We also found that the chitin mother can continue to survive after birth, rather than die quickly Liang Yan, an associate researcher at the Nanjing Institute of Geology and paleontology, Chinese Academy of Sciences, who led the study.
