New late silurian to middle devonian acanthodians of the Timan-Pechora region
New Pridoli to Eifclian acanthodian scales from various structural units of the Timan-Pechora region are described. Among 15 new species and 1 new genus, there are: 10 new species of nostolepids. common members of most of the biostratigraphic associations, the monospecific genus Monosp'ma gen....
