This is the first comprehensive systematic study of the Middle Jurassic scleractinian corals from the Qiangtang block, based on 225 fossil coral specimens collected from the Buqu Formation in the Biluocuo area of northern Xizang (Tibet). Three species of three genera are identified: Montlivaltia zangbeiensis, Pseudocoenia slovenica, and Kobyastraea coquandi. The assemblage is dominated by solitary Montlivaltia (92.44%), with significantly fewer compound colonies of Pseudocoenia (4.89%) and Kobyastraea (2.67%). Comparative analysis reveals that the Qiangtang coral fauna shows strong affinities with contemporaneous Tethyan assemblages, particularly showing the closest similarities to coral communities from East-Central Iran. These findings provide compelling evidence for a close palaeobiogeographic connection between the Qiangtang block and the central Tethyan region during the Middle Jurassic.
