Plant fossils, including branched axes, foliar structures, fructifications, and dispersed spores have recently been discovered from the type section of the Ghost River formation. The megafossils, although commonly fragmentary, suggest a late Middle or early Upper Devonian age for the beds. This discovery suggests that equivalent strata in other regions may also contain plant remains, the discovery of which would add significantly to our knowledge of Devonian floras in western North America.
最近在幽灵河组的标准剖面上发现了植物化石，包括分枝轴、叶状结构、繁殖器官和分散的孢子。这些大化石虽然通常是破碎的，但表明这些岩层的年代为泥盆纪中期晚期或泥盆纪晚期早期。这一发现表明，其他地区的等效地层可能也含有植物遗迹，这些遗迹的发现将大大增加我们对北美西部泥盆纪植物群的了解。
