Morphology and Systematic Position of the Cambrian Zooproblematic Torellella gracilenta Esakova, 1996 (Order Hyolithelmintida Fisher, 1962)

Phosphatic sclerites Torellella gracilenta Esakova, 1996 from the Lower Cambrian Khatyng Member are studied from the Byd’yangaya Section (Tommotian Stage, D. regularis zone, Siberian Platform). The microlayered microstructure of the sclerites of T. gracilenta is studied for the first time. It is suggested that the organisms studied have a polychaete affinity.
