The described actinopterygian—from the Middle Triassic of Canton Graubünden, Switzerland—is a small fish with bones and scales covered with a thick layer of ganoine and with a cranium characterized by large nasal bones sutured medially, an orbital region with an uncommon, large postero-dorsal infraorbital 4+5, possibly one small accessory suborbita...
The actinopterygian (neopterygian, semionotiform) genus Dapedium LEACH is present in the Lower Jurassic (Lower Toarcian) Posidonia Shale of southern Germany with three known species: D. caelatum QUENSTEDT, D. punctatum AGASSIZ and D. pholidotum (AGASSIZ). The taxonomic defi nition of the three taxa is insuffi cient. D. caelatum and D. pholidotum la...
Recent excavations in the Middle Triassic Prosanto Formation (Ladinian, Ct. Grisons, Switzerland) have produced new material
of the genus Besania Brough 1939. These specimens show many previously unrecorded details. Some features differ from those of the type species
Besania micrognathus, and we therefore erect a new species, Besania schaufelberger...
Revision of the genus Peltoperleidus leads to recognition of a single persisting deepened scale row as the main diagnostic feature for the newly established genus Allisolepis gen. nov. The counts of deepened scale rows are taken to be very consistent in all species assigned to Peltoperleidus and Allisolepis gen. nov., since they can be perfectly ma...
Die Strahlenflosser-GattungEoeugnathus Brough, 1939 (Actinopterygii) (alpine Mitteltrias, Ladin) wird anhand neuer Funde aus der Prosanto-Formation Graubündens
(Ost-Schweiz) detailliert beschrieben und ihre systematische Stellung innerhalb der Subdivision Halecomorphi neu bewertet.
Die morphologischen Untersuchungen ergeben, dass die derzeitige Zuo...
A new species of the genus Ctenognathichthys BÜRGIN 1992 has been described. It is called C. hattichi and comes from the Middle Triassic Prosanto Formation (Ladinian) of Canton Grissons (Eastern Switzerland). It is distinguished from the type specimen C. bellouii (DE ALESSANDRI 1910), previously only known from the Middle Triassic of Southern Switz...
Recent excavations in the Prosanto Formation (Middle Triassic, Ladinian, Switzerland) have yielded a large number of specimens of actinopterygian fishes. This new material contains some specimens of the genus Peltoperleidus BÜRGIN et al., 1991. The description of the new species Peltoperleidus obristi sp. nov. is followed by a review of all occurin...

One specimen each of Dapedium caelatum QUENSTEDT 1858, D. pholidotum (AGASSIZ 1832), and D. punctatum AGASSIZ 1835 from the Posidonia shale (Lower Jurassic, lower Toarcian) of Southern Germany were studied. The study revealed the existence of an independent intercalar (D. punctatum), a paired vomer (D. caelatum), an inde-pendent dentary and splenia...
