Multiple branching and attachment structures in cloudinomorphs, Nama Group, Namibia [PDF]
, 2020 The Ediacaran-Cambrian cloudinomorphs, which include Cloudina, are the first putative skeletal metazoans. They have a benthic ecology and tubular, organic, or biomineralized stacked funnel morphologies but an unresolved phylogenetic affinity.

Carbonate sedimentology: An evolved discipline
The Depositional Record, Volume 12, Issue 1, February 2026.Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Palaeoecology of Ediacaran metazoan reefs [PDF]
, 2016 Terminal Ediacaran metazoan reefs (~548-541 Million years ago (Ma)) can be locally substantial and the skeletal metazoans Cloudina riemkeae, C. hartmannae, Namacalathus and Namapoikia produced diverse reef types with complex ecologies in association with

Sedimentology, Volume 72, Issue 2, Page 365-407, February 2025.ABSTRACT The lower Nama Group in southern Namibia contains trace fossils and soft‐bodied and biomineralized macro‐organisms from the terminal Ediacaran Period (ca 550 to 539 Ma), offering insights into early metazoan evolution. Interpretation of the fossilized Nama Group organisms as being preserved in, or very close to, the environments in which they ...

How to engineer a habitable planet: the rise of marine ecosystem engineers through the Phanerozoic
Palaeontology, Volume 67, Issue 5, September/October 2024.Abstract Ecosystem engineers are organisms that modify their physical habitats in a way that alters resource availability and the structure of the communities they live in. The evolution of ecosystem engineers over the course of Earth history has thus been suggested to have been a driver of macroevolutionary and macroecological changes that are ...

Biological Reviews, Volume 99, Issue 1, Page 110-130, February 2024.ABSTRACT The end‐Neoproterozoic transition marked a gradual but permanent shift between distinct configurations of Earth's biosphere. This interval witnessed the demise of the enigmatic Ediacaran Biota, ushering in the structured trophic webs and disparate animal body plans of Phanerozoic ecosystems.

New Cloudina-like morphotype from the Ediacaran Tamengo Formation (Neoproterozoic, Corumbá Group), Southwest Brazil [PDF]
, 2010 The late Ediacaran index fossil Cloudina Germs is known for its funnel-in-funnel tubular calcareous shell. The Brazilian species Cloudina lucianoi (Beurlen and Sommer) occurs in limestones of the Tamengo Formation, near the top of the Corumbá Group, in ...
