ABSTRACT The earliest Actinoptergyii (ray-finned fishes) and Sarcopterygii (lobe-finned fishes) have been studied intensely, and a consistent picture of interrelationships has begun to emerge for the latter. In contrast, there has been minimal documentation of the pattern of character acquisition leading to the osteichthyan crown. We review the synapomorphies proposed for various levels within osteichthyan phylogeny (total group; Acanthodes + crown group; crown group; Sarcoptergyii… Expand
FRONTIERS IN PALAEONTOLOGY THE EARLY EVOLUTION OF RAY-FINNED FISHES
Ray-finned fishes (Actinopterygii) constitute approximately half of all living vertebrate species. A stable hypothesis of relationships among major modern lineages has emerged over the past decade,Expand

The characters of Palaeozoic jawed vertebrates
TLDR
A clearly stated hierarchy of synapomorphies covering the jaw-bearing stem gnathostomes and osteichthyan and chondrichthyan stem groups is provided and a proposed synapomorphy scheme is used to evaluate the status of the problematic fossil groups Acanthodii and Placodermi. Expand
Ray-finned fishes (Osteichthyes, Actinopterygii) from the type Maastrichtian, the Netherlands and Belgium
TLDR
All convincing records of ray-finned fishes from the Maastrichtian of the Netherlands and Belgium, inclusive of the Mons Basin, are teleosts, and include both stem- and crown-group members. Expand
The Oldest Actinopterygian Highlights the Cryptic Early History of the Hyperdiverse Ray-Finned Fishes
TLDR
Phylogenetic analysis places Meemannia as an early-diverging ray-finned fish, resolving it as the sister lineage of Cheirolepis plus all younger actinopterygians, and fills a conspicuous faunal gap in the otherwise diverse late Silurian-earliest Devonian vertebrates of the South China Block. Expand
A new stem sarcopterygian illuminates patterns of character evolution in early bony fishes
TLDR
A new lobe-finned fish Ptyctolepis brachynotus dating from the Early Devonian is described, which preserves a novel combination of cranial characters and suggests revision of evolutionary relationships among bony fish. Expand
The largest Silurian vertebrate and its palaeoecological implications
TLDR
The largest pre-Devonian vertebrate described is a predatory marine osteichthyan from the Silurian Kuanti Formation of Yunnan, China, with an estimated length of about 1 meter, and this finding refutes the assumption that pre-Emsian vertebrates were restricted to small body sizes. Expand
Endoskeletal structure in Cheirolepis (Osteichthyes, Actinopterygii), An early ray‐finned fish
TLDR
Re‐examinations of existing museum specimens through the use of high‐resolution laboratory‐ and synchrotron‐based computed tomography scanning reveal new details of the neuro‐cranium, hyomandibula and pectoral fin endoskeleton for the Eifelian Cheirolepis trailli, helping clarify primitive conditions within ray‐finned fishes. Expand
Styracopterid (Actinopterygii) ontogeny and the multiple origins of post-Hangenberg deep-bodied fishes
TLDR
It is shown that styracopterid growth series show that trunk depth increased during maturation, mirroring the shape variation observed among the Eurynotiformes, and implies that platysomoids are polyphyletic: deep-bodied and/or durophagous fishes evolved multiple times following the Hangenberg event.

Major issues in the origins of ray‐finned fish (Actinopterygii) biodiversity

  • Biology, Medicine
  • Biological reviews of the Cambridge Philosophical Society
  • 2014
TLDR
The systematics and characteristics of these major ray‐finned fish clades, and the early fossil record of Actinopterygii, are reviewed, in order to gauge the sources of doubt. Expand

Styloichthys as the oldest coelacanth: Implications for early osteichthyan interrelationships
TLDR
A revised cladistic analysis places Styloichthys as the most basal coelacanth, which, if correct, fills conspicuous stratigraphic and morphological gaps in the fossil record of this clade. Expand
Morphology and Interrelationships of Primitive Actinopterygian Fishes
TLDR
It is concluded that Cladistia are the sistergroup of Recent actinopterygians (Actinopteri), the two groups together comprising the Actinoperygii, and Recent chondrosteans are more closely related to higher act inopts than to cladistians. Expand
The oldest articulated osteichthyan reveals mosaic gnathostome characters
TLDR
The discovery of an exceptionally preserved primitive fish from the Ludlow of Yunnan, China, that represents the oldest near-complete gnathostome (jawed vertebrate) offers insights into the origin and early divergence of osteichthyans, and indicates that the minimum date for the actinopterygian–sarcoperygian split was no later than 419 million years ago. Expand
A primitive sarcopterygian fish with an eyestalk
TLDR
A basal sarcopterygian fish is described that fills the morphological gap between Psarolepis and higher sarcoptergyians and the presence of eyestalk attachments is reported, showing that this supposedly non-osteichthyan feature occurs in basal sarcoperygians as well as the actinoptergyian-like Australian braincase. Expand
XII.—The Postcranial Skeleton of Rhipidistian Fishes Excluding Eusthenopteron
TLDR
The postcranial remains of other Rhipidistia are now described as far as they are known, and comparisons are made with Eusthenopteron and other forms where relevant, and possible modes of function are considered. Expand
A review of the lower actinopterygian phylogeny
TLDR
It is concluded that the Cladistia are the sister group of Recent actinopterygians (Actinopteri) and that the extinct Palaeonisciformes are a paraphyletic group, comprising stem-group actinopsians (e.g. Cheirolepis) and relatives of higher actinopterans such as Pteronisculus. Expand
The most primitive osteichthyan braincase?
TLDR
The discovery of the oldest and most primitive actinopterygian-like osteichthyan braincase known is reported, from 400–million-year-old limestone in southeastern Australia, which provides an important and unique counterpart to the similarly aged and recently described Psarolepis from China and Vietnam.

CHARACTER DIAGNOSIS, FOSSILS AND THE ORIGIN OF TETRAPODS
TLDR
A recent review by Rosen et al. (1981) claims that Dipnoi (lungfish) are the sister‐group of the Tetrapoda, that Osteolepiformes is a non‐taxon and that Eusthenopteron is more distant from tetrapods than are Dip noi, coelacanths and probably the fossil Porole piformes, are refuted by use of the same cladistic technique.

A NEW ACTINOPTERYGIAN FROM THE FAMENNIAN OF EAST GREENLAND AND THE INTERRELATIONSHIPS OF DEVONIAN RAY-FINNED FISHES
TLDR
The scheme of relationships suggests that actinopterygians invaded freshwater environments at least four times during the Devonian, while age constraints indicate that many of the cladogenic events between ingroup taxa included in this study occurred during or before the Givetian. Expand
Dipnoan (lungfish) skulls and the relationships of the group: a study based on new species from the Devonian of Australia
Four new species of dipnoan fishes (lungfishes) are described from the Frasnian of Western Australia: Griphognathus whitei, Chirodipterus australis, C. paddyensis and Holodipterus gogoensis. TheseExpand
