Three hundred and forty-six articulated fossil specimens of two species from the Middle or Upper Jurassic Karabastau Formation of the Karatau Range (Kazakhstan, Asia) were studied to revise two little-known palaeonisciform fish: Pteroniscus turkestanensis and Morrolepis aniscowitchi. Detailed morphological analysis shows that P. turkestanensis, Daqingshaniscus longiventralis and Uighuroniscidae form a closely related group. They are far more distantly related to the Palaeoniscidae than… 
A new genus of coccolepidid actinopterygian from the Cretaceous Iguanodon-bearing locality of Bernissart, Belgium
Abstract The Barremian–Aptian (Cretaceous) locality of Bernissart, Belgium is mainly known for the Iguanodon skeletons it yielded. Nonetheless, it also delivered a rich actinopterygian fauna. Among
Diversity of chondrostean fish Coccolepis from the Late Jurassic Solnhofen Archipelago, Southern Germany
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
Pterosaur material from the uppermost Jurassic of the uppermost Morrison Formation, Breakfast Bench Facies, Como Bluff, Wyoming, including a pterosaur with pneumatized femora
Abstract Pterosaur fossils are rare in the Morrison Formation, and most are poorly preserved. The Breakfast Bench Facies (BBF) at Como Bluff produces incomplete but uncrushed limbs. One proximal and
Systematic revision of the Cretaceous actinopterygian fauna from Bernissart , Belgium
The Cretaceous locality of Bernissart, Belgium, is well known for the Iguanodon remains it yielded. Fossils were collected during coalmine exploitation at the end of the 19th century. In the frame of
Early Cretaceous polar biotas of Victoria, southeastern Australia—an overview of research to date
Poropat, S.F., Martin, S.K., Tosolini, A.-M.P., Wagstaff, B.E, Bean, L.B., Kear, B.P., Vickers-Rich, P. & Rich, T.H., May 2018. Early Cretaceous polar biotas of Victoria, southeastern Australia—an


The rhadinichthyids (paleoniscoid actinopterygians) from the Bear Gulch Limestone of Montana (USA, Lower Carboniferous)
These fishes probably fed by suction, either at the bottom of the water column or by intake of floating nutritive particles, and were probably mechanical adaptations for a greater widening of the mouth cavity during abduction of the mandible.
Possible link connecting reptilian scales with avian feathers from the early Late Jurassic of Kazakstan
Organic tissue of a recently found second specimen of feather-like Praeornis from the Karabastau Formation of the Great Karatau Range in southern Kazakstan, has a stable carbon isotope composition

Phylogenetic analyses recover Mimipiscis and Gogosardina as sister genera within a monophyletic Mimiidae, a clade restricted to the Late Devonian of Western Australia.
Diversity and size changes in palaeonisciform fishes (Actinopterygii, Pisces) from the Pennsylvanian Mazon Creek fauna, Illinois, U.S.A.
Seven palaeonisciform species can be recognized in the Middle Pennsylvanian Mazon Creek fauna of Illinois, U.S.A, and two of the five “Elonichthys” species with denticulated scales are new, “E.” peltigerus and ” hypsilepis,” while two new species with smooth scales are placed in new genera.
Biological aspects of an interesting fossil fish: Paramblypterus duvernoyi (Amblypteridae, Actinopterygii)
Compared to most other lower actinopterygians, certain modified features regarding the suspensory apparatus, snout bones, gape, dermohyal and suborbital region, and palaloquadrate-maxillary chamber, are present in Paramblypterus duvernoyi, suggesting an increased versatility of the skull and/or enlargement of underlying muscles, thus improving the ability of food uptake.
Identifying patterns of diversity of the actinopterygian fulcra
Revised definitions of fin rays, scutes or ridge scales, and fulcra have been traditionally interpreted as modified scales, but their diversity has been almost ignored and their phylogenetic implications remain to be investigated.
It is shown that Tarrasiids are monophyletic and are the sister group of the other analysed Actinopteri, which supports the most recent studies in indicating that TARRasiidae are close to stem actinopterygians.
Fish from the freshwater Lower Cretaceous, near Koonwarra, Victoria, Australia : with comments on the palaeo-environment
Freshwater Lower Cretaceous sediments near Koonwarra, Victoria, Australia, and the vertebrate fauna contained in them are described. The evolutionary implications of the fish fauna are considered in
Mesozoic fish faunas of China
The information on the geographical and geological occurrences and composition of Mesozoic fish faunas of China summarized in this paper shows successive changes of major groups of actinopterygians
Iyalepis nom. nov., a new replacement name for Angarichthys Sytchevskaya et Yakovlev, 1985 (Pisces, Palaeonisciformes, Coccolepididae)
Sytchevskaya and Yakovlev (1985) described a new genus and species of coccolepidid palaeonisc, Angarichthys rohoni , from the Early–Middle Jurassic of the Baikal Region (Angara River Basin, locality
