Concentrations of Silurian nautiloid cephalopods from Russia and Kazakhstan
Olga K. Bogolepova and Charles H. Holland
Silurian cephalopod limestones known from northern Asia are usually singular beds or horizons of nodules. They range in their taphonomic character from the Mojero river type, with postmortem concentration from rich living populations by relatively gentle bottom currents into a submarine low, to that of the Karabutak Formation of the South Urals, where there has been concentration by strong wave or current action.
Key words: Nautiloid cephalopods, concentrations, Silurian, Russia, Kazakhstan.
