The Petalodontiformes are Upper Paleozoic marine euchondrocephalan chondrichthyans known primarily from isolated teeth. Few dentitions have been reported, among them that of the Permian Janassa bituminosa and “Janassa” korni and the Serpukhovian, Mississippian Belantsea montana, Obruchevodus griffithi, Netsepoye hawesi and Siksika ottae. A dentition has been reconstructed for the Pennsylvanian Petalodus ohioensis. New information on dentitions and postcranial morphology is now introduced for… 

First Record of Petalodus Owen, 1840 (Chondrichthyes, Petalodontidae) in the Lower Permian (Cisuralian) of China

The Petalodontiformes are a small intriguing group of Permo–Carboniferous chondrichthyans. Petalodus is the longest known petalodont genus generally considered representative of the order. The first

Case 3779 – Petalodus Owen, 1840 (Chondrichthyes, Petalodontiformes, Petalodontidae): proposed conservation of usage by designation of a neotype for its type species Petalodus hastingsii Owen, 1840

The Commission is asked to exercise its plenary power to set aside the misleading and inadequate holotype, NHM UK PV P613, and designate as neotype specimen NHMUK PV P75414, a more complete tooth that shows all the characteristic features of Petalodus.

Carboniferous chondrichthyan assemblages from the Surprise Canyon and Watahomigi formations (latest Mississippian–Early Pennsylvanian) of the western Grand Canyon, Northern Arizona

Abstract Two chondrichthyan assemblages of Late Mississippian/Early Pennsylvanian age are now recognized from the western Grand Canyon of northern Arizona. The latest Serpukhovian Surprise Canyon

Ecomorphology of the Mississippian fishes of the Bear Gulch Limestone (Heath formation, Montana, USA)

These analyses lend new insight into the adaptive radiations of Chondrichthyes and Osteichthyes subsequent to the Upper Devonian mass extinctions.

Holocephali From the Irati Formation (Paraná Basin), Brazil: Origin, Paleogographical and Paleoenvironmental Considerations

The Permian (Cisuralian) Irati Formation, from the Brazilian southeastern Paraná Basin bears, at some levels, Chondrichthyes, besides other vertebrates, which is an argument for a proposed isolation of two Brazilan Basins northeast Parnaíba and southeast Paraná, during the time of deposition of the Irati.

The Taquaral Member, Irati Formation (Paraná Basin, Permian): a synthesis of paleontological studies

The Irati Formation (Cisuralian, Kungurian) is noteworthy for many sedimentological, paleontological and taphonomic features, of great significance for unweaving paleoenvironmental details of

A critical appraisal of appendage disparity and homology in fishes

Identifying homologies of morphological traits across large phylogenetic scales is not always straightforward, as many structures are likely to have accrued changes in morphology and function over evolutionary time.

Family-group names of fossil fishes

The main goal of the list is to contribute to the usage of the correct family-group names for fossil fishes with a uniform spelling and to list the author(s) and date of those names.

Fin modules: an evolutionary perspective on appendage disparity in basal vertebrates

The results suggest that the pectoral/pelvic fins and the dorsal/anal fins form two distinct evolutionary modules, and that the latter is nested within a more inclusive median fins module.

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.

Morphological examination of fossil chondrichthyans indicates that the plesiomorphous state of the gnathostome suspensorium is autodiastylic and that complex labial cartilages are primitive and likely to have been critical to the mechanical architecture of the first jaws.
