Ecological interactions in Cloudina from the Ediacaran of Brazil: implications for the rise of animal biomineralization

Abstract At the Ediacaran/Cambrian boundary, ecosystems witnessed an unparalleled biological innovation: the appearance of shelled animals. Here, we report new paleoecological and paleobiological data on Cloudina, which was one of the most abundant shelled animals at the end of the Ediacaran. We rep...
