摘要

A specific group of tubular microfossil Eosolenides, which display a series of biological innovations for these organic-walled microorganisms, is reported from the Meso-Neoproterozoic boundary beds (Lakhanda Microbiota, 1 Ga). This morphologically diverse group is recognized by the presence of unicellular symbionts and by an external narrowly-segmented integument, a supposed cuticle. Appearance of outer covers in the evolution of early organisms could be related to calcium, and calcium imbalance could explain sharp changes in morphology of some Eosolenides.
