Eighty-six species of bivalves belonging to 49 genera are identified. Seventy-four species are described. Eleven of them are new: Lopatinia callomoni, Modiolus elongatus, Aguilerella aldingeri, Camptonectes milnelandensis, Tancredia magna, ?Pronoella superjurensis, Isocyprina birkelundi, Hartwellia borealis, Goniomya bicarinata, Pleuromya triangularis, and Pleuromya zakharovi. One new subspecies, Limatula consobrina multicostata is also described, and two new subgenera are erected: Strimodiolus and Costicamptonectes. The autecology of each species is discussed and comprehensive faunal lists, which include the remaining benthic invertebrates, are given for each member.
