摘要
Abstract
The shell microstructure of the rare lingulate genus Praeoehlertella Mergl, 2001 from the Famennian of Kazakhstan is studied. The structure of the shell matrix and the secondary granular layer are studied using scanning electron microscope. Imprints of cells of the inner mantle epithelium are discovered.
