Diversity and systematics of calcified cyanobacteria and associated microfossils in Cambrian Series 2 shallow-marine carbonates, Yangtze Platform, South China
Randomized trial reports diversity of calcified cyanobacteria in Cambrian Series 2, indicating significant prehistoric links.
Key Points
This research aims to systematically investigate calcified cyanobacteria and associated microfossils from Cambrian Series 2 carbonates on the Yangtze Platform.
Surveyed 10 shallow-marine carbonate sections from the Cambrian Series 2, including reefal and non-reefal types.
Identified 15 species across 10 genera of calcified cyanobacteria and 5 species across 3 genera of Microproblematica.
Documented 2 new species and compared assemblages with those from Siberian and North China.
Identified 15 genera of calcified cyanobacteria, indicating a widespread presence in early Cambrian shallow-marine environments.
First report of several genera from South China, significantly advancing the fossil record.
Showed close resemblances between calcified assemblages of the Yangtze Platform and those from other regions, supporting global distribution.
