十字珊瑚科(Stauriidae)在我国志留系中是最为常见的化石类型之一。它广泛分布于四川、贵州、云南、湖北等地,其次在陕西、湖南、甘肃、新疆、安徽、江西、江苏等地也都有发现。就其特征而言,这类珊瑚是皱纹珊瑚中具有独特的壁内隔壁分裂繁殖方式的一类,因此,对于十字珊瑚科的研究,不论在生物演化或是地层划分上都具有十分重要的意义。 Stauriidae is one of the most common fossil types in the Silurian in China. It is widely distributed in Sichuan, Guizhou, Yunnan, Hubei and other places, followed by Shaanxi, Hunan, Gansu, Xinjiang, Anhui, Jiangxi and Jiangsu. As far as their characteristics are concerned, this kind of coral is one of the most distinctive types of fission and multiplication in the wall-walled coral. Therefore, the research on the family Araliaceae is of great significance both in biological evolution and stratigraphic division .
