Life history and autecology of an Ediacaran index fossil: Development and dispersal of Cloudina [PDF]
Gondwana Research, 2015 Abstract Cloudina is the best-known biomineralizing metazoan and a potential index fossil in the late Ediacaran Period, yet many aspects of its biology remain poorly understood. Previous reports have shown that Cloudina tubes grow from a basally closed funnel (or apical element), with occasional dichotomous branching.

The puzzle assembled: Ediacaran guide fossil Cloudina reveals an old proto-Gondwana seaway
Geology, 2014 ABSTRACTDuring the Ediacaran the Clymene Ocean separated the Lau-rentia, Amazonia, and Rio Apa cratons from several landmasses to the west forming the proto-Gondwana supercontinent. However, no clear evidence about the existence of Ediacaran epeiric seas over those landmasses has been found.

Some observations on Cloudina, a terminal Proterozoic index fossil from Namibia
Journal of African Earth Sciences, 2001An overview is provided of past and present concepts about Cloudina, a Neoproterozoic tube-building organism, significant for its early use of biomineralisation. In the past, Cloudina tubes from the Nama limestones of Namibia have had to be studied in thin- or polished sections, but some observations are reported here on silicified tubes extracted ...

Abstract The genus Cloudina Germs, 1972 includes seven species restricted to Ediacaran strata: 1. Cloudina lucianoi (Beurlen and Sommer, 1957) (Tamengo Formation, Brazil); 2. Cloudina hartmanae Germs, 1972 (Nama Group, Namibia); 3. Cloudina riemkeae Germs, 1972 (Nama Group, Namibia; 4.

Taxonomy of the late Ediacaran index fossil Cloudina and a new similar taxon from South China
Precambrian Research, 2017Abstract Cloudina is a late Ediacaran tubular fossil known from almost every continent. It is typically a mm- to cm-sized conical tube consisting of multiple, nested, funnel-shaped elements, forming the diagnostic “funnel-in-funnel” tube construction.

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 ...

Abstract The Navalpino anticline of the Central Iberian Zone provides a unique case study of well-exposed late Ediacaran reefs. Drone images show their spatial arrangement as tens of shelly-microbial patch, biohermal and complex reefs encased in a dominantly shaly succession.

ACloudina-like fossil with evidence of asexual reproduction from the lowest Cambrian, South China
Geological Magazine, 2017AbstractThe earliest fossil record of animal biomineralization occurs in the latest Ediacaran Period (c. 550 Ma).CloudinaandSinotubulitesare two important tubular taxa among these earliest skeletal fossils. The evolutionary fate ofCloudina-type fossils across the Ediacaran–Cambrian transition, however, remains poorly understood.
