Palaeozoic arthropods in Baltoscandian erratics from the coastal cliffs near Gdynia in northern Poland

Geologos
Fossils recovered from Baltoscandian erratic boulders and cobbles, collected on the beach near Orłowo and Oksywie Cliff (the latter for the first time) near Gdynia in northern Poland constitute an interesting lot.

An electron backscatter diffraction study of geesops: a broader view of trilobite vision? [PDF]

, 2008
The calcite eyes of trilobites have been studied for over 100 years using methods including light microscopy (e.g. Clarke 1889; Campbell 1975; Towe 1973; Clarkson 1979 and Bruton and Haas 2003) and more recently cathodoluminescence (CL) imaging coupled ...

Resource use, niche width, and trophic position reveal diverse trophic structure in a tidal freshwater zone fish community

Journal of Fish Biology, Volume 106, Issue 6, Page 1876-1888, June 2025.
Abstract The tidal freshwater zone is an aquatic transition zone that links a river to its estuary and provides an important habitat used in the life cycle of resident and migratory fishes. Yet, information on the trophic structure of fishes in this habitat is scarce. To address this gap, we characterize the trophic structure of a fish community in the

A new euarthropod from the Soom Shale (Ordovician) Konservat‐Lagerstätte, South Africa, with exceptional preservation of the connective endoskeleton and myoanatomy

Papers in Palaeontology, Volume 11, Issue 2, March/April 2025.
Abstract A new exceptionally preserved euarthropod, Keurbos susanae gen. et sp. nov. from the Upper Ordovician Soom Shale Konservat‐Lagerstätte of South Africa, is described herein. Two specimens exhibit an unusual preservation style such that the cuticular exoskeleton is preserved in low relief but retains high‐fidelity details, whereas the internal ...

Moulting in Ordovician dalmanitoid and acastoid trilobites of the Prague Basin. Preliminary observation

Geologica Acta, 2005
A review of the supposed moulting positions of the Bohemian Ordovician dalmanitoid and acastoid trilobites is presented. Five main moulting positions are described, but some combinations of these are also widespread.
