Cloudina-Corumbella-Namacalathus association from the Itapucumi Group, Paraguay: Increasing ecosystem complexity and tiering at the end of the Ediacaran [PDF]
Precambrian Research, 2017 Abstract The intriguing Ediacaran fossil Namacalathus is described from limestones of the Tagatiya Guazu Formation, Itapucumi Group, Paraguay. This is the fifth occurrence of the genus in the Ediacaran geological record. The Paraguayan Namacalathus specimens are preserved as partially complete spheroidal cups with an opening at the top and thin ...

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.

Oxygen, Ecology, and the Cambrian Radiation of Animals [PDF]
, 2013 The Proterozoic-Cambrian transition records the appearance of essentially all animal body plans (phyla), yet to date no single hypothesis adequately explains both the timing of the event and the evident increase in diversity and disparity.

Developing proxies to constrain redox gradients in terminal Ediacaran oceans [PDF]
, 2015 There is a long-standing interest in the relationship between the rise of early Metazoans and changes in the redox structure of the oceans. As such, there is a need for reliable geochemical proxy archives that record palaeo-redox.

Revisiting the Ediacaran-Cambrian boundary in the Ossa-Morena Zone (SW Iberia) [PDF]
, 2019 Some of the best outcrops of Iberia to study the Ediacaran-Cambrian boundary are located in the Ossa- Morena Zone. In the Crato-Campo Maior region (SW Iberia, Portugal), this stratigraphic boundary is marked by an angular unconformity (Gonçalves, 1971 ...

Macroevolution and macroecology through deep time [PDF]
, 2007 The fossil record documents two mutually exclusive macroevolutionary modes separated by the transitional Ediacaran Period. Despite the early appearance of crown eukaryotes and an at least partially oxygenated atmosphere, the pre-Ediacaran biosphere was ...
