Abstract
The first occurrence of the problematic cnidarians Sphenothallus Hall (S. sp. 1 and S. sp. 2) is described from upper Viséan and ?Bashkirian (Carboniferous) black shales of the Dnipro-Donets Depression in NE Ukraine. Carboniferous Sphenothallus spp. from the Dnipro-Donets Depression apparently led an epifaunal gregarious lifestyle, preferring paleobasin areas with slow sedimentation rates, low current energy, and dysaerobic environments, as already suggested by literature data. The discovery of representatives of the genus Sphenothallus in Carboniferous strata of Ukraine significantly extends our knowledge about the geographic distribution of these animals. Further, it confirms their preference for environments with slow sedimentation. Keywords: cnidarians, Sphenothallus, Carboniferous, Dnipro-Donets Depression, Ukraine.
问题刺胞虫Sphenothallus Hall (S. sp. 1和S. sp. 2)的首次出现是在乌克兰东北部第聂伯-顿涅茨凹陷石炭系vissaman上部和Bashkirian下部黑色页岩中发现的。来自第聂伯-顿涅茨凹陷的石炭纪sphenthallus似乎过着一种脚外群居的生活方式，更喜欢沉积速率慢、电流能量低、缺氧环境的古盆地地区，正如文献数据所表明的那样。在乌克兰石炭纪地层中发现的蝶属代表，极大地扩展了我们对这些动物地理分布的认识。进一步证实了它们对缓慢沉积环境的偏好。关键词:刺胞动物，石炭纪，石炭纪，第聂伯-顿涅茨大萧条，乌克兰
