Cretaceous bryophyte fossils are known only from a few localities and only a few are known in ultrastructural fidelity. We describe a fossil moss gametophyte from Upper Cretaceous Taimyr amber and place it in the fossil genus Taimyrobryum martynoviorum gen. et sp. nov. (Bryopsida). Its unbranched, somewhat zig-zagged stems with distantly spaced, spreading, narrowly lanceolate leaves and the unbranched costa match the gross morphology of Dicranidae; however, the uniformly prosenchymatous leaf cells contradict an affiliation to this subclass. The Yantardakh in the Taimyr Peninsula is the fourth and northernmost Cretaceous amber locality yielding inclusions of bryophytes.
