Early diagenetic evolution based on petrography and stable isotope analysis in the Barra Velha Formation of the Brazilian Pre‐salt

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 70-94, February 2025.
Mineralogy and texture of diagenetic phases in the Aptian Pre‐Salt Barra Velha Formation are described, quantified and compared by facies and structural setting to understand their spatial and temporal distribution, and to develop predictive concepts for their genesis.

The role of organic matter in Brazilian Pre‐Salt carbonates

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 403-417, February 2025.
Diverse types of organic matter (OM) were identified in Brazilian Pre‐Salt carbonates. The presence of OM along and inside calcite structures indicates a strong microbial influence in Brazilian Pre‐Salt carbonate precipitation. The occurrence of these organic compounds in distinguishing facies raises the discussion of biotic versus abiotic genesis of ...

A peritidal Burgess‐Shale‐type fauna from the middle Cambrian of western Canada

open access: yesPalaeontology, Volume 68, Issue 1, January/February 2025.
Abstract Burgess‐Shale‐type (BST) faunas have proven critical for mapping the Cambrian assembly of animal‐dominated ecosystems, but have so far only been reported from fully subaqueous deposits. Here we integrate evidence from ichnofossils, sedimentary features, and small carbonaceous fossils (SCFs) from the middle Cambrian (Late Guzhangian, Series 3 ...

Effects of two different deep digital flexor tenotomy techniques on distal articular angles of equine cadaver forelimbs Efeito de duas técnicas de tenotomia do flexor digital profundo sobre os ângulos articulares distais dos membros anteriores de equinos: estudo post-mortem

open access: yesCiência Rural, 2012
Deep digital flexor (DDF) tenotomy is a technique employed for years to treat selected disorders of the musculoskeletal system in horses. Although two different surgical approaches (i.e.

Morphological abnormalities and apoptosis in lamellar tissue of equines after intestinal obstruction and treatment with hydrocortisone

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
Four experimental groups of equines were used in order to study morphological abnormalities and apoptosis in lamellar tissue. Group Cg (control) was composed of animals without any surgical procedure; group Ig (instrumented), animals that underwent ...

Advances in Limnogeology: The lake‐basin‐type model revisited 25 years after…anomalies, conundrums and upgrades

open access: yesThe Depositional Record, Volume 10, Issue 5, Page 748-792, November 2024.
This manuscript is a review of the lake basin type models applied in Limnogeology, their evolution since the last update (2000), integration with new data and finally the presentation of a new lake basin type model proposal as a result of this process. It is intended as a novel and useful contribution for the Limnogeology community.

Ultrastructural Perspectives on the Biology and Taphonomy of Tonian Microfossils From the Draken Formation, Spitsbergen

open access: yesGeobiology, Volume 22, Issue 6, November/December 2024.
ABSTRACT Silicified peritidal carbonates of the Tonian Draken Formation, Spitsbergen, contain highly diverse and well‐preserved microfossil assemblages dominated by filamentous microbial mats, but also including diverse benthic and/or allochthonous (possibly planktonic) microorganisms. Here, we characterize eight morphospecies in focused ion beam (FIB)
