A new psammosteid (Agnatha, Heterostraci) from the Amata Regional Stage of the Main Devonian Field and morpho-histological types of discrete micromeric elements in the family Psammosteidae [PDF]
Estonian Journal of Earth Sciences, 2017 In memory of an outstanding palaeoichthyologist Elga Mark-Kurik The range of diversity of psammosteids from the family Psammosteidae is still poorly known. Here a new species, Psammosteus ramosus sp. nov.

Meteoritics &Planetary Science, EarlyView.Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure
Meteoritics &Planetary Science, EarlyView.Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.

Palaeoecological reconstruction of the Late Devonian Lebedjan biota
, 2022 Palaeozoic fossil-bearing deposits in Russia record important and rare insights into pre-Mesozoic palaeoecological systems. Among the known formations, the Late Devonian (Famennian) deposits exposed in the central part of Russian platform have been under-

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes
New Phytologist, EarlyView.Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Sedimentology, EarlyView.ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern
