在这些中泥盆世或可能是下泥盆世地层中，只发现了一种显微镜下的甲壳类动物（成体长约3毫米），即LeP-IDOCARIS rhyniensis*（第155页）。它的关系需要建立一个新的目的和家庭的鳃足类：脂甲，鳞-caridae。由于燧石的半透明性质，几乎可以重建动物的所有外部细节。不同发展阶段的两性都有代表和形象。它的一些细节似乎对甲壳类动物附属物的进化有重要的启示。除了L之外，没有任何“池塘生活”生物的痕迹。rhyniensis的发现似乎证实了这一理论，即Rhynie燧石层沉积的水可能是热的，并且富含二氧化硅。[See也是进入之后的。
Only 1 micro-scopic crustacean (adult about 3 mm. in length), LEP-IDOCARIS rhyniensis* (p. 155), has been found in these Middle or possibly Lower Devonian beds. Its relationships necessitate the erection of a new order and family of Branchiopoda: LIPOSTRACA, LEPIDO-CARIDIDAE. Owing to the semi-transparent nature of the chert, it has been possible to reconstruct the animal in practically all external details. Both sexes in various stages of development are represented and figured. Some of its details seem to throw important light on the evolution of crustacean appendages. The absence of all certain traces of "pond-life" organisms other than L. rhyniensis seems to confirm the theory that the water in which the Rhynie Chert Bed was deposited may have been hot and highly charged with silica.
