Abstract：
:The fossil dinosaur bone material, 80 million years old was studied. Samples for analysis were prepared with specially elaborated methods. Images obtained in the light, transmission electron, and scanning electron microscopes revealed the spatial distribution of the osteocytes lying near and far from the vascular canal. Osteocytes of particular kind were found to be present in the immediate vicinity of the canal. The characteristic morphological structure and the localization of this osteocytes between the vascular canal and the osteocytes lying farther from the canal, as well as the mediation of this cell in the system of connections between those elements, served as a basis for the separation of this cells as the intermediary osteocyte. Among the osteocytes situated farther from the vascular canal, three kinds were distinguished: mono-, bi-, and multipolar, according to the kinds of processes and their distribution in relation to the mother cell body. By analogy with modern bone, in dinosaur bone specific functions may be ascribed to the distinguished types of osteocytes and to their differentiated processes in the conduction of nutrient and building elements and metabolites from the vascular canal to the intermediary osteocytes and, with their participation, to other osteocytes lying farther from the canal. This should naturally be analysed as the two-way tract.
