N2 - Here we present the first description and images of foraminiferal fauna from the carbonate cobbles and pebbles of Early Jurassic polymicticconglomerates from Graham Bell Island, in the easternmost part of the Franz Joseph Land archipelago. The composition of the conglomeratessuggests a proximal provenance area. The identified foraminiferal genera and species suggest a Serpukhovian–Late Carboniferous age for theprimary carbonates from which the conglomerate clasts were derived, and which can be correlated with coeval carbonate strata of Svalbard, theVolga–Urals and the Pechora region. Combined with previous studies, our new data lead us to assert that a shallow-marine carbonate platformoccupied the entire Barents shelf, including its northeasternmost part, during Carboniferous–Early(?) Permian time. This study improves ourunderstanding of the composition and age of pre-Mesozoic successions of Franz Joseph Land and surrounding parts of the Barents Sea.
