A research team led by Associate Professor Wang Yaqiong from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS), in collaboration with colleagues from multiple domestic and international institutions, has for the first time documented two marine ostracod fossil species—Bicornucythere bisanensis s.l. and Pistocythereis bradyformis—in Pleistocene lacustrine deposits of the Qaidam Basin. The findings were recently published in the journal Palaeoentomology.
