二叠纪前的苔藓植物记录仅限于中泥盆世和晚泥盆世以及宾夕法尼亚地层中数量非常有限的地钱，以及推测的中奥陶世的地钱。苔藓植物的稀少，尤其是石炭纪明显缺乏苔藓，是引人注目的，因为这个时间间隔的特点是大面积湿地环境的出现，这些湿地环境可能提供了理想的栖息地。我们报告了来自德国东部密西西比河的三种苔藓，它们是迄今为止已知的最古老的明确苔藓。尽管材料不完整，但这些发现表明苔藓是石炭纪生态系统的一部分。苔藓残留物是通过大量浸渍获得的，这种方法并不常用于研究石炭纪植物区系。我们预计，将这种方法应用于来自其他石炭纪地区的材料将表明，苔藓在古生代晚期比以前认为的更为广泛。
The pre-Permian record of bryophytes is restricted to a very limited number of liverwort occurrences in Middle and Late Devonian and in Pennsylvanian strata, and a putative liverwort from the Middle Ordovician. The paucity of bryophytes, notably the apparent absence of mosses in the Carboniferous, is striking because this time interval is marked by the occurrence of extensive wetland environments that likely provided ideal habitats. We report three types of mosses from the Mississippian of eastern Germany that are the oldest unequivocal mosses known to date. Although the material is fragmentary, these finds show that mosses formed part of Carboniferous ecosystems. The moss remains were obtained by bulk maceration, a method that is not commonly used for studying Carboniferous floras. We anticipate that applying this method on material from other Carboniferous localities will show that mosses were more widespread in the late Paleozoic than previously thought.
