An assemblage of microfossils of moderate diversity, with the remarkable occurrence of ECAP acritarchs, is reported from the Ediacaran Krol ‘A’ (= the Mahi Formation) succession of Lesser Himalaya, India. Microfossils occur in the chert nodules exposed in Solan district, Himachal Pradesh. Two microfossils, Barogophycus symmetricus n. gen. n. sp. and Botominella lineata are new to the well-established Krol assemblage. The paper concentrates predominantly on fossil eukaryotic filamentous and coccoidal micro-organism of simple morphology. The assemblage is dominated by remains of prokaryotic cyanobacteria and demonstrates the diversity achieved by microorganisms at the beginning of the Ediacaran Period in the aftermath of the Marinoan glaciation. Filamentous and coccoidal microorganisms differ in taxonomic composition from the Mesoproterozoic microbiotas. The Krol microfossils assemblage has biostratigraphic potential and usefulness in broadly demarcating the different levels of the Ediacaran strata. Because of the presence of ECAP acritarchs, along with the appearance of other eukaryotic microorganisms of filamentous and coccoidal morphology, the general level of the Krol ‘A’ assemblage is considered as Ediacaran.

据报道，来自印度小喜马拉雅山的埃迪卡拉克罗尔 'A'（= Mahi 组）系列的中等多样性的微化石组合，显着出现了 ECAP acritarchs。微化石出现在喜马偕尔邦索兰地区出露的燧石结核中。两个微化石，Barogophycus symmetricus n。将军 n. sp. 和波托米纳线虫是成熟的 Krol 组合的新成员。该论文主要集中于形态简单的真核丝状和球状微生物化石。该组合以原核蓝细菌的遗骸为主，并展示了埃迪卡拉纪初期马里诺冰川之后微生物所实现的多样性。丝状和球状微生物的分类组成与中元古代微生物群不同。Krol 微化石组合在广泛划分埃迪卡拉纪地层的不同层次方面具有生物地层学潜力和用途。由于 ECAP acritarchs 的存在，以及其他丝状和球状形态的真核微生物的出现，Krol 'A' 组合的一般水平被认为是 Ediacaran。
