托盖是俄罗斯贝加尔湖奥尔洪岛的一个地区，这里出产了中新世晚期或中新世晚期早期的蛇类动物群。它所在的地区很广阔，但尚未有新近纪蛇的报告；因此，它是一个重要的里程碑。该动物群包括一种非马铃薯科动物、两种或三种蛇类、一种蝰蛇属“东方复合体”的蝰蛇科动物，也许还有另一种蝰蛇科动物。这种组合令人惊讶地让人想起来自西欧和中欧的早中新世晚期和中新世早期的蛇类动物群，据了解，中新世动物群在地理中间区域实际上是未知的。中新世期间，欧亚大陆（除大陆南部地区外）是否居住着同质的蛇类动物群，这一点值得思考。
Togay, a locality from Ol’khon Island, Baykal Lake, Russia, has yielded a fauna of snakes of Late Middle or early Late Miocene age. It is located in a broad area from which no Neogene snake has been reported; therefore, it represents an important landmark. The fauna includes a non-erycine boid, two or three colubrids, a viperid of the ‘oriental complex’ of Vipera, and perhaps another viperid. This assemblage is astonishingly reminiscent of the snake faunas from the late Early and early Middle Miocene from western and central Europe, it being understood that Miocene faunas are practically unknown in the geographically intermediary area. It may be entertained whether a homogenous snake fauna inhabited Eurasia (except the southern part of the continent) during the Miocene.
