Quick Summary

The Maplewell Series is a subdivision of the Charnian rocks, which are part of the Late Precambrian geological period in England. These rocks are primarily volcanic, with sedimentary conglomerates, sandstones, siltstones, and slates also present. The Maplewell Series is notable for containing impressions of Charnia, an ancient Precambrian organism whose exact classification is debated, with theories ranging from algae to coelenterates. The Charnian rocks, including the Maplewell Series, are found in the Charnwood Forest and Midlands regions of England and are comparable to the Stretton Series of the Eastern Longmyndian.1
