The Miocene lacustrine carbonate factory of the Ñirihuau Formation, Ñirihuau Basin, North Patagonian Andes, Argentina

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 147-181, February 2025.
Detailed sedimentologic, petrographic and geochemical analyses of the lacustrine deposits registered on the Ñirihuau Formation middle section in the northern sector of the Ñirihuau Basin are presented. The lacustrine carbonates found within these deposits were analysed to characterise the palaeolake system as well as the carbonate factory of the basin,

Multi‐Parameter Investigation of Cretaceous to Palaeocene Sedimentary Sequences in the Anambra and Niger Delta Basins, Nigeria: Organic Matter Characterisation, Palynofacies and Implications for Palaeoclimate and Sea‐Level Changes

open access: yesGeological Journal, Volume 60, Issue 1, Page 196-222, January 2025.
The study examines Cretaceous to Palaeogene sedimentary sequences in the Anambra Basin, part of West African rift basins, utilising geochemical and palynological interpretations to understand organic matter accumulation. Palynofacies and geochemical data indicate a predominantly warm and humid tropical climate during a time of widespread marine ...

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 ...

Hydrocarbon‐derived thrombolites from the Outer Carpathians (Lower Cretaceous, Poland)

open access: yesSedimentology, Volume 71, Issue 7, Page 2183-2209, December 2024.
Abstract Shallow marine thrombolites from a newly discovered Lower Cretaceous cold seep in the Outer Carpathians (Poland) were analysed in order to untangle the complex sedimentological and biogeochemical processes involved in their formation and their diagenetic modifications.

Reworked acritarchs as provenance indicators in the Lower Palaeozoic of Denmark [PDF]

open access: yes, 2001
Profuse and well-preserved acritarchs were recovered from subsurface Lower Palaeozoic successions cored by the boreholes Slagelse-1 and Pernille-1 (Danish-North German Basin).

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)
