A palaeocoastline reconstruction for the Käsmu and Pärispea peninsulas (northern Estonia) over the last 4000 years [PDF]

open access: yesEstonian Journal of Earth Sciences, 2012
The marine-freshwater environmental transition, i.e. basin isolation from the Limnea Sea, has been identified in two short sediment cores with respect to their diatom composition, loss-on-ignition and magnetic susceptibility content.

Łódź Region and its Northern Vicinity under Vistulian Glaciation Conditions

open access: yesQuaestiones Geographicae, 2014
An overview of palaeogeographical findings of the last glacial period (MIS 5d-MIS 2) has been given for the Łódź region. Processes which influenced the area outside of ice-sheet margin are presented with respect to space and time, as predominantly driven

Lower Wenlock black shales in the northern Holy Cross Mountains, Poland: Sedimentary and geochemical controls on the Ireviken Event in a deep marine setting [PDF]

open access: yes, 2016
The stratigraphic variability and geochemistry of Llandovery/Wenlock (L/W) Series boundary sediments in Poland reveals that hemipelagic sedimentation under an anoxic/euxinic water column was interrupted by low density bottom currents or detached diluted ...

The onset of grasses in the Amazon drainage basin, evidence from the fossil record [PDF]

open access: yes, 2020
Poaceae (the grass family) originated in the Cretaceous, but first dominate the palynological records of the Amazon drainage basin (ADB) in the Neogene (23 to 2.5 million years ago (Ma)).

Devonian corals of the Vosges Mountains, France [PDF]

open access: yesActa Palaeontologica Polonica
The Saxo-Thuringian Zone of western Europe is a tectonostratigraphic unit that includes Devonian sediments. Usually, the sediments are deep-water siliciclastics and variously affected by regional metamorphism.
