The assessment of fossils in sediments and sedimentary rocks often involves the destruction of the sedimentary matrix and even of parts of the fossil assemblage (e.g. via removing and/or dissolution). Therefore, the destruction-free assessment of fos

Previous myological studies show inconsistencies with regard to the identification and naming of the shoulder joint muscles in frogs and toads (Amphibia: Anura). Those inconsistencies were revealed and resolved by assessing the ontogenetic developmen

Computed‐tomography‐derived (CT‐derived) polymesh surfaces are widely used in geometric morphometric studies. This approach is inevitably associated with decisions on scanning parameters, resolution, and segmentation strategies. Although the un
