Researchers have discovered new groups of moss plants in Amber, Myanmar

NANJING, April 18 (Xinhua) -- According to China's
Nanjing Institute of Geology and Paleontology, the Institute has conducted in-depth research on amber moss plants in Kachin State, Myanmar, and discovered new groups of moss plants through collaboration with researchers from the
Xishuangpana Tropical Botanical Garden and the China
Plant Research Institute.
the study was recently published in the international geostatological journal Cretaceous Research.
recent years, there has been positive progress in paleontical research in Cretaceous amber, but fewer moss plants have been understood and reported. Recently,
Wang Yongdong, Dr. Li Ya, Researcher of Nanjing Institute of Geology and Paleontology, Harald Schneider,
Xishuangpuna Tropical Botanical Garden of China, and Wu Pengcheng Researcher of china
Plant Research Institute collaborated to conduct in-depth research on amber moss plants in the middle cretaceous period of Kachin State, Myanmar, and achieved a series of results.
team reported on a relatively intact and anatomical fossil of the ear-leaf Tycole leaf moss, and established a new species of deep-cracked ear-leaf moss.
It is understood that the main features of the new group named deep-cracked ear-leaf moss are the long egg-shaped or oval-shaped back flaps of the side lobes of the nutrition branch, the tip of the leaf with fine tip, the appendage is large and obvious, and the abdominal leaves are deeply cracked. The nutrient branches of the present species of ear-leaf moss do not have deep-cracked abdominal leaves, and only a few of the reproductive branches of the living species have deep-cracked female abdominal leaves.
researchers said that most species of light moss are endophytes, including light moss, ear-leaf moss and other 7 departments. Molecular system development studies show that moss plant light moss increased significantly in the rate of diversification during the Cretaceous Tetanary Revolution, but the fossil evidence is very small.
moss is the most common moss plant in the new generation of amber fossils, but by comparison there is little record in Cretaceous amber, usually composed of small fragments rather than complete plants.
, only a few species, such as polycystic moss, flat moss and ear-leaf tesco, have been reported in Cretaceous amber in Myanmar. The discovery of deep-cracked ear-leaf moss represents a new advance in the fossil species of myanmar Cretaceous amber biome Ear-leaf Tesco, which has accumulated fossil evidence for further study of the radiation and diversity evolution of light moss-eared moss in the middle cretaceous period.
