Abstract

Two occurrences of Middle Ordovician opercula belonging to the gastropod Maclurites are described, one from the Taimyr Peninsula, Siberia, and one from the Kuskokwim Mountains, Alaska. The Taimyr opercula are the first to be described from Russia. Like other opercula of the genus, these thick specimens have a relatively massive prong on the interior to which the retractor muscle was attached. The Alaskan specimens preserve a secondary muscle attachment site. The described occurrences of Maclurites opercula are summarized.
