Papers in Palaeontology, Volume 9, Issue 4, July/August 2023., 2023 Abstract Among ray‐finned fishes (Actinopterygii), the crushing, durophagous feeding strategy first evolved in the early Carboniferous period, with the †Eurynotiformes possessing dentitions with single layers of partially to fully fused blunt teeth.

A new Pycnodontid (Actinopterygii) in the late Jurassic of the Solnhofen Archipelago [PDF]
Research & Knowledge, 2017 Pycnodontiformes are an extinct order of Actinopterygian fishes, present from the Late Triassic (Norian) to the Eocene. With their mostly deep, laterally compressed bodies and comparatively large fins, these fishes were mostly highly manoeuvrable reef ...

A Piranha-like Pycnodontiform Fish from the Late Jurassic [PDF]
Current Biology, 2018 Pycnodontiformes are an extinct order of ray-finned fishes from the Triassic to Eocene [1, 2], with a characteristic crushing dentition reflecting a highly specialized diet [3]. However, our discovery of a new pycnodontiform from the Late Jurassic (ca.

Peculiar tooth renewal in a Jurassic ray‐finned fish (Lepisosteiformes, †Scheenstia sp.)
Palaeontology, Volume 63, Issue 1, Page 117-129, January 2020., 2020 Abstract Tooth replacement in vertebrates is extremely diverse, and its study in extinct taxa gives insights into the evolution of the different dental renewal modes. Based on μ‐CT scans of a left lower jaw of the extinct fish †Scheenstia (Actinopterygii, Lepisosteiformes), we describe in detail a peculiar tooth replacement mode that is, as far as we ...

Late Triassic pycnodont fish remains (Neopterygii, Pycnodontiformes) from the Germanic basin
Eclogae Geologicae Helvetiae, 2004 Isolated dental remains of pycnodont fishes are recorded from the upper Norian (Upper Triassic) of the Germanic basin for the first time. The only complete prearticular dentition differs significantly from those of other Late Triassic pycnodonts such as Brembodus and Eomesodon.

Early Jurassic diversification of pycnodontiform fishes (Actinopterygii, Neopterygii) after the end-Triassic extinction event: evidence from a new genus and species, <i>Grimmenodon aureum</i>. [PDF]
J Vertebr Paleontol, 2017 A new genus and species of pycnodontiform fishes, Grimmenodon aureum, from marginal marine, marine-brackish lower Toarcian (Harpoceras exaratum ammonite subzone) clay deposits of Grimmen in northeastern Germany is described. The single specimen represents a diagnostic left prearticular dentition characterized by unique tooth arrangement and ...

STUDIES ON PYCNODONT FISHES (I): EVALUATION OF THEIR PHYLOGENETIC POSITION AMONG ACTINOPTERYGIANS
Rivista Italiana di Paleontologia e Stratigrafia, 2015 One of the main pending, unsolved problems concerning the study of the pycnodont fishes is their phylogenetic relationships with other major actinopterygian groups.

European Journal of Taxonomy, 2014 The osteology of “Coccodus” lindstroemi is studied in detail and it is demonstrated that this species does not belong to the genus Coccodus, but is a rather primitive member of the pycnodontiform family Gladiopycnodontidae. Indeed, the snout of “Coccodus”

Stable isotope study of a new chondrichthyan fauna (Kimmeridgian, Porrentruy, Swiss Jura): an unusual freshwater-influenced isotopic composition for the hybodont shark Asteracanthus [PDF]
Biogeosciences, 2015 Chondrichthyan teeth (sharks, rays, and chimaeras) are mineralized in isotopic equilibrium with the surrounding water, and parameters such as water temperature and salinity can be inferred from the oxygen isotopic composition (δ18Op) of their bioapatite.
