Synopsis The Early Devonian (Lochkovian) sarcopterygian fish Styloichthys has been interpreted as the immediate sister taxon of the clade comprising both the dipnoan and the tetrapod total groups, but support for this placement is weak. Many derived characters of the lower jaw, braincase and dermal skull align Styloichthys with coelacanths and their bearing on the affinities of this genus is set against the evidence in support of earlier interpretations. A revised cladistic analysis places… Expand
A Reappraisal of the Origin and Basal Radiation of the Osteichthyes
TLDR
This distribution of characters is used to interpret the placement of problematic Siluro-Devonian genera traditionally assigned to Actinopterygii, and suggests these taxa are stem osteichthyans. Expand
A reappraisal of the origin and basal radiation of the Osteichthyes
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 theExpand
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
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
Earliest known coelacanth skull extends the range of anatomically modern coelacanths to the Early Devonian.
TLDR
The earliest known coelacanth skull (Euporosteus yunnanensis sp. nov.) from the Early Devonian (late Pragian) of Yunnan, China is reported, lending support to the possibility that Eoactinistia is also an anatomically modern coelacanths, and provides a more refined reference point for studying the rapid early diversification and subsequent evolutionary conservatism of the coELacanths. Expand
Neurocranial anatomy of an enigmatic Early Devonian fish sheds light on early osteichthyan evolution
TLDR
A second skull of ‘Ligulalepis’ is described and micro-CT data is presented to reveal novel anatomical features, including cranial endocasts, which are shown to be variable in its development between specimens. 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
A new Early Cretaceous coelacanth from Texas
Coelacanths have a long fossil record spanning from Early Devonian to the present globally, but until now only from Permian and Triassic sediments in Texas. Reported here is a partial skull,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
The Giant Cretaceous Coelacanth (Actinistia, Sarcopterygii) Megalocoelacanthus dobiei Schwimmer, Stewart & Williams, 1994, and Its Bearing on Latimerioidei Interrelationships
TLDR
The cladistic analysis supports the sister-group relationship of Megalocoelacanthus and Libys within Latimeriidae and suggests that toothless, large-sized coelacanths evolved independently in both Latimer iidae and Mawsoniidae during the Mesozoic. Expand

Oldest coelacanth, from the Early Devonian of Australia
TLDR
The discovery of a new coelacanth from the Early Devonian of Australia is reported, which fills in the approximately 20 Myr ‘ghost range’ between previous coelacanths records and the predicted origin of the group. Expand
A newly recognized fossil coelacanth highlights the early morphological diversification of the clade
TLDR
Coelacanths have long had an iconic place in the study of vertebrate evolution for their apparent anatomical conservatism over geological time, but Holopterygius provides clear evidence for rapid morphological evolution early in the history of this clade. Expand
The First Tetrapod Finds from the Devonian (Upper Famennian) of Latvia
TLDR
The lower jaw of Ventastega is strikingly primitive in retaining fangs on the coronoid series, but shares many characters with those of other known Devonian tetrapods, and some of these features are interpreted as basal tetrapod synapomorphies. 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
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. Expand
ON THE RELATIONSHIPS OF PSAROLEPIS AND THE ONYCHODONTIFORM FISHES
TLDR
Some aspects of the anatomy of the new Gogo Onychodus are compared with recently described material of Psarolepis, the oldest known possible sarcopter ygian fish, which have immediate bearing on competing schemes of basal osteichthyan phylogeny. 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 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
EARLY TETRAPOD JAWS FROM THE LATE DEVONIAN OF PENNSYLVANIA, USA
TLDR
A new Late Devonian tetrapod, Densignathus rowei, is described, based on a well-preserved lower jaw, characterized by dramatic widening of the jaw anterior of the adductor fossa, a pronounced twist in the orientation of ventral margin of the jaws, and weakly-developed radiating ornament on the lateral surface of the infradentaries.
