古生物学的相关性必须以原则为指导，其中一些原则是从对生物体及其分布的研究中得出的。在应用这些原则，9植物区带在北极石炭纪的宾夕法尼亚州的植物区系省被认为是。包括的植物区系都是低地，温暖气候，雨林组合。在落基山脉地区出现了某些被认为代表高地植物群的植物群类型。在舌到石炭纪的地区，宾夕法尼亚植物群的差异很大，被认为是代表煤气候，雨林组合。这些组合的几个代表被认为是，和一些北极石炭纪的元素被认为是移民在一个时代的气候温和。
Paleontologic correlation must be guided by principles, some of which are stated here, derived from a study of living organisms and their distribution. In application of these principles, nine floral zones in the Arcto-Carboniferous province of Pennsylvanian floras are considered. The floras included are all lowland, warm-climate, rain forest assemblages. In the Rocky Mountain area certain floral types appear that are thought to represent upland floras. In the Antarcto-Carboniferous province the Pennsylvanian floras differ greatly in the main and are believed to represent coal-climate, rain forest assemblages. A few representatives of these assemblages are considered, and a few Arcto-Carboniferous elements present are regarded as immigrants during an epoch of milder climate.
