Environmental and diagenetic controls on the morphology and calcification of the Ediacaran metazoan Cloudina [PDF]
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]
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]
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

Ediacaran-Cambrian paleosols of Nevada and California. [PDF]
The 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]
The 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 ...

The Ediacaran-Cambrian Radiation of Animals within the Villuercas-Ibores-Jara UNESCO Global Geopark, Spain [PDF]
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
