In North Vietnam, Lower to Middle Triassic storm- and wave-dominated shelf deposits are widely exposed and yield abundant Tethyan bivalves indicating recovery and diversification following the end-Permian mass extinction. We reconstructed the habitat

Lower Triassic bivalve assemblages are recognized in the Yinkeng Formation, South China, and the Hong Ngai Formation, North Vietnam. Basinal mudstones and deep ramp carbonates contain the mono- specific Claraia wangi assemblage. The Eumorphotis teilh

Two Permian-Triassic boundary sections (Lung Cam and Nhi Tao) in shallow marine carbonates from northern Vietnam, near the border between Vietnam and China, were studied for major and trace elemental variations as well as carbon and oxygen isotopic c

Liassic ammonites from the Nong Son basin are rare, and little diversified. The fossil record is restricted to two fossiliferous beds. The ammonites display original features with the genera Ectocentrites (E. dommerguesi nov. sp. et E. kherucensis no
