Tube growth patterns and microbial mat-related lifestyles in the Ediacaran fossil Cloudina, Gaojiashan Lagerstätte, South China

Gondwana Research, 2014
Abstract Cloudina are important Ediacaran index fossils, as they have a consistent terminal Neoproterozoic age and a worldwide distribution. The morphology of Cloudina has been reconstructed primarily on the basis of three-dimensionally preserved Chinese and Spanish specimens, but questions remain surrounding their phylogenetic placement ...

Spygoria zappanianew genus and species, aCloudina-like biohermal metazoan from the Lower Cambrian of central Nevada

Journal of Paleontology, 1999
A new enigmatic Lower Cambrian fossil,Spygoria zappania,is described From theNevadellazone (Botoman) of Lander County, central Nevada. In gross morphology,Spygoriafossils consist of stacks of small (5–10 mm in diameter) irregular calcified cups that are preserved in vertical, concave-up life orientation.

Shell structure and distribution of Cloudina, a potential index fossil for the terminal Proterozoic.

American journal of science, 1996
Cloudina-bearing biosparites and biomicrites in the lower part of the Nama Group, Namibia, contain a wide morphological diversity of shell fragments that can all be attributed to the two named species C. hartmannae and C. riemkeae. The curved to sinuous tubular shells of Cloudina were multi-layered.
