Abstract
In the Devonian sections of the Southern Tien Shan, a group of ostracods was found, the shells of which have characteristic trapezoidal outlines and a significantly expanded and flattened ventral side. The study of the structure of the free edge of these shells allowed us to distinguish among them two groups, differing from each other primarily by the presence or absence of the internal calcified lamina ...
