Ecological interactions in Cloudina from the Ediacaran of Brazil: implications for the rise of animal biomineralization
TLDR
The close association of Cloudina tubes with microbial mat textures as well as organic-rich material, syndepositional calcite and goethite cement between their flanges are reported, thus reinforcing the awareness of metazoan/microorganism interactions at the end of the Ediacaran.
Deciphering the preservation of fossil insects: a case study from the Crato Member, Early Cretaceous of Brazil
TLDR
It is considered that biofilms of sulphate reducing bacteria (SRB) had a central role in insect decay and mineralisation and shed light on exceptional preservation of fossils by pyritisation in a Cretaceous limestone lacustrine palaeoenvironment.
QUATERNARY MAMMALS FROM CENTRAL BRAZIL (SERRA DA BODOQUENA, MATO GROSSO DO SUL) AND COMMENTS ON PALEOBIOGEOGRAPHY AND PALEOENVIRONMENTS
Studies regarding Quaternary mammals from the Serra da Bodoquena (South-western Brazil, state of Mato Grosso do Sul) are scarce. In the region, the Fadas Cave has been an important paleontological
Clay templates in Ediacaran vendotaeniaceans: Implications for the taphonomy of carbonaceous fossils
Although rare, sedimentary deposits containing exceptionally preserved fossils (i.e., Lagerstätten) have shaped our view on the history of life at particular intervals, such as those recording the
GEOBIOLOGICAL AND DIAGENETIC INSIGHTS FROM MALVINOKAFFRIC DEVONIAN BIOTA (CHAPADA GROUP, PARANÁ BASIN, BRAZIL): PALEOBIOLOGICAL AND PALEOENVIRONMENTAL IMPLICATIONS
Abstract: This study tests the presence of differential preservation in the Devonian Malvinokaffric fauna from the Chapada Group (Paraná Basin, Brazil). Results of EDXRF, EDS, Raman Spectroscopy, and
The role of volcanic-derived clays in the preservation of Ediacaran biota from the Itajaí Basin (ca. 563 Ma, Brazil)
TLDR
It is shown that a number of minerals can facilitate preservation, and that perhaps ‘Ediacaran-style’ preservation result from different processes leading to the same broad style of preservation.
