Environmental and diagenetic controls on the morphology and calcification of the Ediacaran metazoan Cloudina [PDF]
Scientific Reports, 2021 Cloudina is a globally distributed Ediacaran metazoan, with a tubular, funnel-in-funnel form built of thin laminae (ca. 1–10 μm). To what degree local environmental controlled morphology, and whether early diagenesis controlled the degree of ...

Ecological interactions in Cloudina from the Ediacaran of Brazil: implications for the rise of animal biomineralization [PDF]
Scientific Reports, 2017 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 ...

Enduring evolutionary embellishment of cloudinids in the Cambrian [PDF]
Royal Society Open Science, 2021 The Ediacaran–Cambrian transition and the following Cambrian Explosion are among the most fundamental events in the evolutionary history of animals. Understanding these events is enhanced when phylogenetic linkages can be established among animal fossils

Sesgo tafonómico en los datos de distribución de Cloudina en Siberia
Estudios Geologicos, 2019 En Siberia los morfotipos de Cloudina han sido tradicionalmente considerados como una variedad tafonómica de conchas de Anabarites, insertadas una dentro de otra, bajo condiciones hidrodinámicas específicas.

Multiscale approach reveals that Cloudina aggregates are detritus and not in situ reef constructions. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance Little is known about how the Ediacaran index fossil Cloudina lived and what impact it had on its surroundings. This uncertainty is due to the fact that Cloudina often is preserved with the same mineralogy as the rocks in which it is found; the lack of density contrast ...

Ediacaran-Cambrian paleosols of Nevada and California. [PDF]
PLoS ONEThe Cambrian and Ediacaran sequence of California and Nevada is rife with unconformities, paleovalleys, paleosols, and fluvial facies. This study confirms shallow marine environments for grey stromatolitic dolostone and shale of northern localities (Mt ...

New insight into the global record of the Ediacaran tubular morphotype: a common solution to early multicellularity [PDF]
Royal Society Open ScienceThe tubular morphogroup is a common component of Earth’s first complex, multicellular communities—the Ediacaran biota—and offers valuable insight into biological traits that are fundamental to animal life because they have intriguing links to metazoan ...

Taxonomic revision of Ediacaran tubular fossils: Cloudina, Sinotubulites and Conotubus [PDF]
Journal of Paleontology, 2021 AbstractThe Ediacaran tubular fossils Cloudina, Sinotubulites, and Conotubus are taxonomically revised with type materials. It is proposed that Aulophycus lucianoi Beurlen and Sommer, 1957, is not a senior synonym of Cloudina hartmannae Germs, 1972. Instead, most of its syntypes may be assigned to Sinotubulites or other taxa.

The Ediacaran-Cambrian Radiation of Animals within the Villuercas-Ibores-Jara UNESCO Global Geopark, Spain [PDF]
Geoconservation Research, 2021 Across the Ediacaran to Cambrian transition, some 541 Ma, the Earth's biosphere changed from one dominated by microbial organisms to one where multicellular organisms, including animals, rose to importance. Within a few tens of millions of years into the
