Taxonomic revision of Ediacaran tubular fossils: Cloudina, Sinotubulites and Conotubus [PDF]

open access: yesJournal of Paleontology, 2021
. The 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.

Cloudina aggregates from the uppermost Dengying Formation, Three Gorges area, South China, and stratigraphical implications

Precambrian Research, 2022
Numerous issues remain concerning palaeobiology, palaeoecology, and biostratigraphy of Cloudina, an iconic tubular organism of the Ediacaran period. In this study, accumulations of Cloudina are described from the topmost bed of the Dengying Formation in the Baiguotang section of the eastern Three Gorges area, South China.

New materials reveal Shaanxilithes as a Cloudina-like organism of the late Ediacaran

Precambrian Research, 2021
Abstract Shaanxilithes is a potential index fossil of late Ediacaran for its cosmopolitan occurrences and narrow stratigraphic range. However, its morphology and taxonomy has long been controversial and its biological affinities remain problematic, with interpretations ranging from pogonophorans, sedimentary structures, trace fossils, algae, to ...

Cloudina-microbial reef resilience to substrate instability in a Cadomian retro-arc basin of the Iberian Peninsula

Precambrian Research, 2020
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.
