Marine environment and fauna at Hot House Earth during the Early Triassic

俄罗斯南滨海地区下三叠统的地层和化石组合表明，由于海洋缺氧延伸至近海海底的影响，海洋生物的栖息环境不在风暴波底部以下。早在斯巴斯蒂安人就认识到了溶解缺氧的先见之明。由于菊科类、海百合类和双壳类在斯巴斯蒂亚期间是多样化的，这种海洋恢复将导致海洋生物的重组。

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.
