- Abstract
Lower Cretaceous Buchia (Bivalvia) from little known localities of Transcaucasia and Kamchatka are figured and described for the first time; a brief overview of all known finds of this genus in the Lower Cretaceous of the regions under consideration and the areas of the North Caucasus adjacent to Transcaucasia is given. The findings of Buchia inflata in Kamchatka made it possible to clarify (to the early Valanginian) the age of the host rocks, while Hauterivian B. keyserlingi in Azerbaijan are the youngest finds of the genus in the Tethyan succession. The assessment of the biostratigraphic and biogeographic significance of new Buchia finds is given.
