Special Issue Information

Dear Colleagues,

Actinopterygii are a highly diverse and evolutionarily successful group of ray-finned fishes, full-filling important roles in all aquatic environments on Earth. Their fossil record extends back into the Early Devonian and they are characterized by astonishing morphological and correlated taxonomic diversity throughout their evolutionary history. As extant ray-finned fishes, their extinct relatives adapted to a large variety of habitats and occupied almost all tropic levels in aquatic systems. However, despite all progress that has been accomplished in recent decades employing morphology and molecular genetics, many ambiguities concerning the taxonomy and systematics of fossil and recent fishes continue to persist.

In this Special Issue, we present the latest findings on ray-finned fishes, focusing on the morphology, taxonomy, systematic, distribution, abundance, and diversity patterns of fossil and living ray-finned fishes, as well as how anthropogenic factors impact fish communities today. Specific topics include, but are not limited to, the following: (1) the importance of fossil remains of fishes (scales, bones, otoliths, teeth, skeletons, coprolites, and trace fossils) for taxonomy and systematics; (2) the evolutionary history of Actinopterygii; (3) the diversity and biogeographic patterns of ray-finned fishes in deep time, (4) the ecology of extinct and extant ray-finned fishes, and (5) anthropogenic impacts on fishes and fish communities.

Please do not hesitate to contact us if you are interested in contributing to this Special Issue, which is intended to form a refernce work on actinopterygian research for both professionals and students, or if you have any questions.

Pycnodont fishes were a successful clade of neopterygian fishes that are predominantly found in shallow marine deposits. However, throughout their long 180 million year reign (Late Triassic–end Eocene), they made multiple incursions into both brackish and freshwater environments. This fossil record mostly consists of fragmentary dental material, but articulated specimens are known from Early Cretaceous lacustrine localities in Spain. This review article aims to document all non-marine occurrences of Pycnodontiformes throughout most of the Mesozoic and early Paleogene. This review highlights two interesting trends in the history of non-marine habitat colonization by pycnodonts: (1) a huge spike in non-marine occurrences during the Cretaceous; and (2) that most occurrences in non-marine localities occurred at the latest Cretaceous period, the Maastrichtian. The high number of colonization events within the Cretaceous lines up with extreme climatic events, such as high temperatures resulting in high sea levels which regularly flooded continental masses, allowing pycnodonts easier access to non-marine habitats. The increased presence of pycnodonts in brackish and freshwater habitats during the Maastrichtian might have played a role in their survival through the K/Pg extinction event. Freshwater habitats are not as vulnerable as marine ecosystems to environmental disturbance as the base of their food chain relies on detritus. Pycnodonts might have used such environments as a refuge and began to occupy marine waters after the K/Pg extinction event. Full article
