Unappreciated Cenozoic ecomorphological diversification of stem gars revealed by a new large species [PDF]

open access: yesActa Palaeontologica Polonica, 2022
The evolutionary history of gars, an ancient group of ray-finned fishes, is excellently documented in the fossil record. These fishes are notable for how little the anatomy of extant species differs from that of their earliest known relatives from ...

Diversity of chondrostean fish Coccolepis from the Late Jurassic Solnhofen Archipelago, Southern Germany [PDF]

open access: yesActa Palaeontologica Polonica, 2021
Late Jurassic marine vertebrates are extraordinarily well preserved in several Plattenkalk Lagerstätten in central Europe. Among them, the Solnhofen Archipelago has yielded the very rare fish Coccolepis bucklandi, which was the first fossil ...

Feeding convergence among ray-finned fishes: Teeth of the herbivorous actinopterygians from the latest Permian of East European Platform, Russia [PDF]

open access: yesActa Palaeontologica Polonica, 2020
unique functional adaptation to herbivory within early ray-finned fishes is exemplified by the late Permian actinopterygians within the family Eurynotoidiidae with policuspid teeth strongly modified with respect to the primitive actinopterygian ...

150 million years of freshwater fish biogeography: vicariance or dispersal? [PDF]

open access: yesResearch & Knowledge, 2017
Freshwater fishes are supposedly good case studies to test palaeobiogeographical models because they are attached to land masses, at least primary freshwater fishes, which are unable to cross marine barriers.
