Аннотация
A new species of the phosphatic brachiopod Discinisca suborbicularis (family Discinidae) from the Upper Jurassic of Western Siberia (latitudinal Priob’e) is established. The shell microstructure under protegulum and brephic shell and the microstructure of adult shell (that corresponds to three developmental stages) are described in detail. The shell microstructure of new species considerably differs from Paleozoic discinids and is similar to Recent discinids. D. suborbicularis differs from recent discinids in the presence of protegulum and thicker organophosphatic primary layer.
