Well-preserved material is described of several specimens of Screbinodus ornatus, a small (approximately 1.5 metres long) rhizodontid sarcopterygian, from the Visean (Mississippian, Carboniferous) of Scotland. This species shows numerous ‘typical’ rhizodontid characteristics, such as post-parietals with a median ‘tail’, pectoral lepidotrichia with elongated basal segments, large symphysial tusks on the dentary and a ‘reverse’ overlap relationship between the cleithrum and clavicle. It also… 

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.,

A new onychodont (Osteichthyes; Sarcopterygii) from the Middle Devonian of Morocco and its bearing on early osteichthyan evolution

A new onychodont sarcopterygian is described from the Middle Devonian (Eifelian) of Morocco. Selenodus aquesbiae gen. et sp. nov. is characterized by a unique suite of traits among onychodonts such

A New Species of Rhizodontiform Sarcopterygian Fish (Sarcopterygii: Rhizodontiformes) from the Lower Carboniferous of the Moscow Region

TLDR
The morphological and functional analysis of the teeth of rhizodontids showed that R. serpukhovensis sp.

A Tournaisian (earliest Carboniferous) conglomerate-preserved non-marine faunal assemblage and its environmental and sedimentological context

TLDR
The richness of the fauna runs counter to the assumption of a depauperate nonmarine fauna following the end-Devonian Hangenberg event, and charcoal content highlights the occurrence of fire, with the requisite levels of atmospheric oxygen during that stage.

A fish and tetrapod fauna from Romer's Gap preserved in Scottish Tournaisian floodplain deposits

The end‐Devonian mass extinction has been framed as a turning point in vertebrate evolution, enabling the radiation of tetrapods, chondrichthyans and actinopterygians. Until very recently ‘Romer's

A Devonian tetrapod-like fish reveals substantial parallelism in stem tetrapod evolution

TLDR
A large, lobe-finned fish from the Late Devonian of China disrupts previously accepted stem-tetrapod phylogeny and reveals parallel evolution within the lineage, suggesting that ecological diversity and biogeographical provinciality in the tetrapod stem group have been underestimated.

Fin ray patterns at the fin-to-limb transition

TLDR
Dermal ray anatomy for 3 species of tetrapodomorph fishes is described, showing changes reveal how fins became adapted for interacting with the substrate prior to the fin-to-limb transition and that dorsoventral asymmetry is an important, understudied axis of diversification in paired fins.

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...

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.

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.

Mandibles of rhizodontids: anatomy, function and evolution within the tetrapod stem-group

TLDR
The rhizodontida appears to have been split into two functional units, one comprising the firmly sutured prearticular, coronoids and dentary, the other comprising the firm-sutured infradentaries.

The hyomandibulae of rhizodontids (Sarcopterygii, stem‐tetrapoda)

TLDR
Four hyomandibulae are reported, from three separate localities, which are referable to the Rhizodontida, the most basal clade of stem‐tetrapods, and share a number of characteristics, and are appreciably different from the small number of hymandibULae reported for other fish‐like stem‐TetrapODs.

A NEW SPECIMEN OF SAURIPTERUS TAYLORI (SARCOPTERYGII, OSTEICHTHYES) FROM THE FAMENNIAN CATSKILL FORMATION OF NORTH AMERICA

TLDR
The pectoral fins of Sauripterus were optimized for adduction and flexion against the water column or a solid substrate, suggesting a sister-group relationship between rhizodontids and tetrapods.

Devonian rhizodontids and tristichopterids (Sarcopterygii; Tetrapodomorpha) from East Gondwana

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.
