Abstract

The microstructure of tubes of the genus Hyolithellus from the stratotype sections of the Tommotian and Botomian stages of the Lower Cambrian of the Siberian Platform (Lena, Aldan, Sinyaya rivers) are studied. The tube walls are shown to have a three-layer structure. The microstructure of the outer and inner layers of hyolithellid tubes is described for the first time.
