Morphological disparity of early ammonoids: A geometric morphometric approach to investigate conch geometry

Acta Palaeontologica Polonica, 2023
Fossils of Devonian ammonoids are abundant and well-preserved in the Anti-Atlas of Morocco; as such they provide an invaluable record of regional morphological disparity changes (diversity of shapes) that characterise the first steps of ammonoid ...

Middle Devonian lithostratigraphy of Belgium

Geologica Belgica
The revision of the lithostratigraphic scale of southern Belgium, based on the revised geological map of Wallonia and recent stratigraphic and sedimentological works, has led to the re-definition of 63 lithostratigraphic units for the Middle Devonian Series.

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA

Groundwater, EarlyView.
Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

Bimekizumab efficacy using IHS4 outcomes in hidradenitis suppurativa: Results from BE HEARD I and II

Journal of the European Academy of Dermatology and Venereology, EarlyView.
The majority of bimekizumab‐treated patients shifted from severe to mild and moderate IHS4 stages, and nearly 25% achieved an IHS4 of 0 by Week 48. Bimekizumab led to clinically meaningful improvements across IHS4 outcome measures. These data highlight an opportunity to address the need for effective treatments against draining tunnels.

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.
