Abstract:	The organophosphatic brachiopods of the superfamily Discinoidea, family Discinidae are described from the Upper Jurassic of West Siberia. The protegulum (embryonic shell) preserved in adult shells is for the first time discovered in Mesozoic discinids. The shell microstructure is studied. A new species, Discinisca undata Smirnova, sp. nov., is established.
