The fish assemblage contains also acanthodians, the sarcopterygian Porolepis kureikensis (Vorobyeva 1963) and the actinopterygian (palaeoniscoid) Dialipina markae, found in the eastern part of the Tunguska syneclise, Kotuj River basin (Schultze 1992).

In addition, acanthodian fish scales and a portion of a fin spine, and numerous actinopterygian and sarcopterygian fish scales and tips of actinopterygian teeth from the MNSC were identified by Kenaga and Sellepack (1995).
Unfortunately, identifying the specific taxa that produced them is not possible, but their association with various fossils from acanthodian, actinopterygian, sarcopterygian, and rhipidistian (crossopterygian) fish suggests that any of these are potential sources of the coprolites and nonspiraled cololites.
Fish otoliths are the specialized hard parts of the actinopterygian and sarcopterygian acoustico-lateralis system, situated in the membranous labyrinths in the otic capsules of the neurocranium.

This conglomerate layer corresponds to the 1st oryctocoenosis represented mainly by separate compactly lying bones including large and very large plates, sometimes partly articulated skeletons and aggregates of sarcopterygian scales, as well as many fragments of bones.
