The first results of sporoderm Paleozoic miospora studies have been received using nanotomografiya. They are comparable with the results of investigations in the scanning electron (SEM) and transmission (TEM) microscopes, which confirm the our interpretation of structures of external and internal sporoderm. Nanotomograf allows to carry out complex studies on the various projections sporoderm, visualization, correlation and location of the various structures without violating the integrity of the object and without losing the unique Paleozoic material. It reduces the time previously spent on the preparation of the object to study in SEM and TEM. The nanosculpture exospores its two-layer structure, the thickness of the layers and their location at the Devonian megaspores Krishtofovichia africani Nikitin established.
