Abstract
A new genus and species Monoshanites dentatus gen. et sp. nov., consisting of asymmetrical sclerites of problematic animal organisms belonging to the family Siphogonuchitidae is described from the Khevte-Tsakhir-Nuruu section of Western Mongolia (Tommotian Stage, Beds with Halkieria amorpha, Bayangol Formation). The microstructure of sclerites with a double wall was studied: the inner layer is lamellar; the outer layer is columnar.
