Reconstruction of the evolutionary biogeography reveal the origins and diversification of oysters (Bivalvia: Ostreidae)

•We provide a multi-locus time-calibrated molecular phylogeny for Ostreidae.•The ancestral range reconstruction suggests that Ostreidae originated in the circum-Arctic region in the Early Jurassic.•The major diversifications of Crassostrea is consistent with associated tectonic events.
