Abstract A new specimen of the rhizodontid sarcopterygian, Sauripterus taylori (Sarcopterygii, Osteichthyes), from the Late Devonian (Famennian) Catskill Formation of Pennsylvania consists of a well-preserved right pectoral fin, girdle, and associated scales. Rhizodontid affinity is supported by the unique pattern of overlap between the clavicle and cleithrum, the robustness of the pectoral girdle, the presence of elongate and unjointed lepidotrichia in the pectoral fin, and the pattern of… 
REDESCRIPTION OF THE PECTORAL FIN AND VERTEBRAL COLUMN OF THE RHIZODONTID FISH BARAMEDA DECIPIENS FROM THE LOWER CARBONIFEROUS OF AUSTRALIA
TLDR
A more complete description of the pectoral fin and vertebral column of Barameda indicates that the fin is much wider than previously estimated and that the radius has a morphology more comparable to that of other rhizodontid taxa.
A new genus of rhizodontid (Sarcopterygii, Tetrapodomorpha) from the Lower Carboniferous Horton Bluff Formation of Nova Scotia, and the evolution of the lower jaws in this group
TLDR
Letognathus gen. nov. is described from the Lower Carboniferous (Tournaisian) Horton Bluff Formation, which indicates that rhizodontid jaws primitively bear symphysial tusks; slender recumbent teeth; an anterior projection of the dentary over the anteromesial depression for the median symphysIAL plate and shows the highly derived jaws ofStrepsodus andRhizodus evolved with...
Cranial morphology of the Carboniferous rhizodontid Screbinodus ornatus (Osteichthyes: Sarcopterygii)
TLDR
A phylogenetic analysis finds that rhizodontids are the sister group to all other members of the tetrapod total group (with the exception of Kenichthys), and confirms that resemblances between derived rhizdontids and digited stem-tetrapods such as Acanthostega are due to convergence.
Pectoral girdle and fin anatomy of Gogonasus andrewsae long, 1985: Implications for tetrapodomorph limb evolution
TLDR
A phylogenetic analysis indicates a more stemward position for Gogonasus in a weakly supported clade with other “osteolepidid” taxa, compared to other recent studies placing Gog onasus crownward of osteolespidid fishes and the Tristichopteridae, as the sister taxon to the “Elpistosteglia” + Tetrapoda.
A NEW SPECIES OF BARAMEDA (RHIZODONTIDA) AND HETEROCHRONY IN THE RHIZODONTID PECTORAL FIN
TLDR
Observations of the Australian Lower Carboniferous rhizodontid Barameda suggest a degree of developmental variability (timing, degree of ossification) in the entepicondyle relative to the rest of the humerus, which could be extended to other posterior processes of pectoral fin elements such as the ulnare flange.
New material supports a description and taxonomic revision of Holoptychius ? radiatus (Sarcopterygii, Tristichopteridae) from the Upper Devonian Catskill Formation in Pennsylvania, USA
ABSTRACT. New material from the Upper Devonian (Famennian) Catskill Formation of Pennsylvania, USA, reveals anatomical details previously lacking from the enigmatic fossil species that Newberry
A Gigantic Sarcopterygian (Tetrapodomorph Lobe-Finned Fish) from the Upper Devonian of Gondwana (Eden, New South Wales, Australia)
TLDR
The hypothesis that tristichopterids evolved in Laurussia and later dispersed into Gondwana, and a derived subgroup of large Late Devonian genera dispersed from Gondswana, is inconsistent with the evidence of the new taxon.
A New Look at Carboniferous Rhizodontid Humeri (Sarcopterygii; Tetrapodomorpha)
ABSTRACT The Rhizodontida are a group of tetrapodomorph sarcopterygian fishes with a worldwide distribution in the Devonian and Carboniferous periods. Rhizodontids were first described in the U.K.,
LATE DEVONIAN (FAMENNIAN) LUNGFISHES FROM THE CATSKILL FORMATION OF PENNSYLVANIA, USA
Abstract:  Occurrences of fossil lungfishes (Dipnoi: Sarcopterygii) in the Famennian Catskill Formation of Pennsylvania are reviewed. A nearly complete dermal skull roof is assigned to a new genus
New Description and Diagnosis of Hyneria lindae (Sarcopterygii, Tristichopteridae) from the Upper Devonian Catskill Formation in Pennsylvania, U.S.A.
TLDR
A near-complete cranial specimen collected near Red Hill that was originally diagnosed as Eusthenodon wängsjöi by Thomson (1976) is revised as Hyneria cf.

Second tristichopterid (Sarcopterygii, Osteolepiformes) from the Upper Devonian of Canowindra, New South Wales, Australia, and phylogeny of the Tristichopteridae
ABSTRACT A new tristichopterid, Cabonnichthys burnsi gen. et sp. nov. from the Upper Devonian Mandagery Sandstone near Canowindra, New South Wales, Australia, is the second tristichopterid to be
A new rhizodontiform fish from the Early Carboniferous of Victoria, Australia, with remarks on the phylogenetic position of the group
TLDR
The skull roof of Barameda, gen. nov., differs from that of Osteolepiformes in having a larger extratemporal bone that contacts the intertemporal, by the overlap areas on the interTemporal, and in having fewer snout bones.

TLDR
It is argued that the Rhizodontida evolved on the Gondwanan landmass, and notorhizodon occupies a relatively derived position within the Tristichopteridae, but is contemporary with the earliest and phylogenetically most basal Laurussian members of the group.
Pectoral fins of rhizodontids and the evolution of pectoral appendages in the tetrapod stem-group
TLDR
The pectoral fin skeleton of Rhizodus hibberti, a derived member of the Rhizodontida, is described in detail for the first time, showing that muscular processes of the humerus may have appeared later in tetrapod evolution than previously thought.
The structure and relationships of a new osteolepiform fish from the Late Devonian of Victoria, Australia
A new osteolepiform, Marsdenichthys longioccipitus gen. et sp. nov., is described from the Frasnian lacustrine shales (Avon River Group) near Mt Howitt, central Victoria. Because it has thin
The Devonian tetrapod Acanthostega gunnari Jarvik: postcranial anatomy, basal tetrapod interrelationships and patterns of skeletal evolution
TLDR
Comparison between axial skeletons of primitive tetrapods suggests that plesiomorphic fish-like morphologies were re-patterned in a cranio-caudal direction with the emergence of tetrapod vertebral regionalisation.
IX.—The Postcranial Skeleton of Ensthenopteron foordi Whiteaves *
TLDR
A functional analysis of the skeleton of Ensthenopteron is attempted, suggesting that it resembled the pike in its mode of life and that it may have been capable of short journeys “walking” overland.
New observations on the snouts of rhizodont fishes (Palaeozoic Sarcopterygii)
TLDR
It is revealed that the rhizodontid snout had only one pair of nostrils rather than two as previously suggested, and the protrusion of the lower jaws in Barameda is matched in the three-dimensional Canowindra material and appears to be a real morphological feature.
A complete primitive rhizodont from Australia
TLDR
The new evidence shows that rhizodonts are more remote from tetrapods than are osteolepiform and elpistostegid lobe-fin fishes and the pectoral fin of Sauripteris should not be used as a model limb precursor.
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.
