The stratigraphy and fossil assemblages of the Lower Triassic in South Primorye, Russia reveals that the habitable environment for marine organisms was not resided below the storm wave base because of the influence of marine anoxia extending offshore bottom. The foresight of the dissolving anoxia is recognized at earliest Spathian. Because ammonoids, crinoids and bivalves were diversified during the Spathian, this oceanic recovery would lead the restructuring of marine organisms.

俄罗斯南滨海地区下三叠统的地层和化石组合表明，由于海洋缺氧向近海延伸的影响，风暴波基底以下并不存在海洋生物的宜居环境。早在斯巴达人就认识到溶解性缺氧的先见之明。由于菊石类、海贝壳类和双壳类在Spathian时期多样化，这种海洋恢复将导致海洋生物的重组。
