Redox-sensitive trace element distribution in the Loma Negra Formation in Argentina: The record of an Ediacaran oxygenation event
(Elsevier Science, 2019-09)
The limestones of the Loma Negra Formation provide an excellent opportunity to examine the behaviour of rare earth elements plus yttrium (REY) due to the near-zero diagenetic alteration of the carbonate system. The terrigenous ...
Goldilocks at the dawn of complex life: mountains might have damaged Ediacaran–Cambrian ecosystems and prompted an early Cambrian greenhouse world

Corumbella and in situ Cloudina in association with thrombolites in the Ediacaran Itapucumi Group, Paraguay
(Wiley Blackwell Publishing, Inc, 2011-12)
An in situ assemblage of Cloudina, thrombolites and an ichnofossil (cf. Archaeonassa), together with fragments of Corumbella werneri, is reported here, from a tidally influenced, shallow, lagoonal setting on a carbonate ...
Global or regional? Constraining the origins of the middle Bambuí carbon cycle anomaly in Brazil
(2020-09-15)
The Ediacaran-Cambrian Bambuí Group in Brazil records an anomalously positive excursion in carbonate carbon isotopes (δ13Ccarb) with a sustained plateau of ca. +15‰ (aka the Middle Bambuí Excursion–MIBE). Considering that ...
Alternative interpretations of some earliest ediacaran fossils from China
(2013-03-01)
In a letter to Nature (February, 2011), Xunlai Yuan and collaborators recorded carbon compression fossils from black shales of the Lantian Formation (Ediacaran), southern Anhui Province, South China. The new fossils, ...

Ediacaran paleoenvironmental changes recorded in the mixed carbonate-siliciclastic Bambui Basin, Brazil
(Elsevier B.V., 2019-03-01)
Significant Ediacaran paleoenvironmental changes recorded in the mixed carbonate-siliciclastic Bambui Basin, east-central Brazil, outcrop in one of the best-preserved sites, the Januaria paleo-high. From a detailed strati ...
Comment on: “Chemostratigraphic constraints on early Ediacaran carbonate ramp dynamics, Río de la Plata craton, Uruguay” by Aubet et al. Gondwana Research, Volume 22, Issues 3-4, November 2012, Pages 1073-1090
(Elsevier Science, 2013-04)
The Arroyo del Soldado Group of Uruguay is a key unit for unraveling several, still unsolved cardinal problems in Neoproterozoic research. Thus, we welcome in principle publications contributing to our knowledge of this ...
