The Fossil Record of Ray-Finned Fishes (Actinopterygii) in Greece [PDF]
, 2021 AbstractThe nowadays hyper-diverse clade of Actinopterygii (ray-finned bony fishes) is characterized by a long evolutionary history and an extremely rich global fossil record. This work builds upon 170 years of research on the fossil record of this clade in Greece. The taxonomy and spatiotemporal distribution of the ray-finned fish record of Greece are

Developmental changes of opsin gene expression in ray-finned fishes (Actinopterygii)
Proceedings of the Royal Society B: Biological Sciences, 2022 AbstractFish often change their habitat and trophic preferences during development. Dramatic functional differences between embryos, larvae, juveniles and adults also concern sensory systems, including vision. Here we focus on the photoreceptors (rod and cone cells) in the retina and their gene expression profiles during the development.

First record of fossil fish (Enchodontoidei, Actinopterygii) in the Struganik quarry in Western Serbia [PDF]
Geoloski anali Balkanskoga poluostrva, 2022 This paper presents the first Upper Cretaceous remains of fish in Serbia, discovered near the village of Struganik. This is also the first described find of Mesozoic fish in Serbia. A stone slab with visible contours of an almost complete fish, with a total body length of about 20 cm, was excavated from the Struganik quarry. Most bones are preserved as

, 2020 The Carboniferous radiation of fishes was marked by the convergent appearance of then-novel but now common ecomorphologies resulting from changes in the relative proportions of traits, including elongation of the front of the skull (rostrum).

Phylogenetic relationships of freshwater fishes of the genus Capoeta (Actinopterygii, Cyprinidae) in Iran [PDF]
Ecology and Evolution, 2016 AbstractThe Middle East contains a great diversity of Capoeta species, but their taxonomy remains poorly described. We used mitochondrial history to examine diversity of the algae‐scraping cyprinid Capoeta in Iran, applying the species‐delimiting approaches General Mixed Yule‐Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network

The Diversity of Ray-finned Fishes (Actinopterygii) in Plio-Pleistocene Java
Journal of Tropical Biodiversity and Biotechnology, 2020 Java has been known in the world of Paleontology as a contributor to the findings of Homo erectus fossils, but there are still other fossil findings that have not been identified until now, especially fossil fishes of the subclass Actinopterygii. This research was conducted to recognize the diversity of the actinopterygians fishes in Plio-Pleistocene ...

New pycnodontiform fishes (Actinopterygii, Neopterygii) from the Early Cretaceous of the Argentinian Patagonia [PDF]
Cretaceous Research, 2019 Here we describe new pycnodontiform fish material recovered from the marine Agrio Formation (lower Valanginian-lower Hauterivian) of the Neuquén Province in the south-western of Patagonia, Argentina. The new material include an incomplete skull and an incomplete prearticular dentition.

Acta Ichthyologica et Piscatoria, 2020 An individual of Pigfish, Orthopristis chrysoptera (Linnaeus, 1766), is recorded for the first time for the Mediterranean Sea, raising to six the number of species of the family Haemulidae in the basin. The fish was caught on 12 September 2020 in the harbor of Siracusa (Ionian Sea) by an angler and had an estimated total length of about 16 cm. Possible
