Multiscale approach reveals that Cloudina aggregates are detritus and not in situ reef constructions [Earth, Atmospheric, and Planetary Sciences]

The earliest metazoans capable of biomineralization appeared during the late Ediacaran Period (635–541 Ma) in strata associated with shallow water microbial reefs. It has been suggested that some Ediacaran microbial reefs were dominated (and possibly built) by an abundant and globally distributed tubular organism known as Cloudina. If true, this...
