Until recently the immediate aftermath of the Hangenberg event of the Famennian Stage (Upper Devonian) was considered to have decimated sarcopterygian groups, including lungfish, with only two taxa, Occludus romeri and Sagenodus spp., being unequivocally recorded from rocks of Tournaisian age (Mississippian, Early Carboniferous). Recent discoveries of numerous morphologically diverse lungfish tooth plates from southern Scotland and northern England indicate that at least 10 dipnoan taxa existed… 

Traquair's lungfish from Loanhead: dipnoan diversity and tooth plate growth in the late Mississippian

ABSTRACT Ramsay Heatley Traquair, the eminent Victorian Scottish palaeoichthyologist and museum curator, procured an extensive collection of Palaeozoic fishes from across Scotland with the help of

The rapid evolution of lungfish durophagy

Innovations relating to the consumption of hard prey are implicated in ecological shifts in marine ecosystems as early as the mid-Paleozoic. Lungfishes represent the first and longest-ranging lineage

High lineage survivorship across the end-Devonian Mass Extinction suggested by a remarkable new Late Devonian actinopterygian

TLDR
Detailed anatomical data for an exceptionally preserved but diminutive ray-finned fish from within this gap, ~7 Myr prior to the Devonian-Carboniferous boundary, are presented and a revised model finds parallels in patterns emerging for other clades.

Systematics and description of the lungfish genus Sagenodus from the Carboniferous of the UK

ABSTRACT The Carboniferous lungfish genus Sagenodus is reviewed from all available British specimens and described in detail for the first time. We identify two species exclusive to the UK: Sagenodus

Paedomorphosis and neurocranial ossification in two Devonian lungfishes

TLDR
The neurocrania of two Devonian species, Scaumenacia curta and Pentlandia macroptera, have been micro-CT-scanned and suggest that occasionally pyrite is a preservative rather than a destructive diagenetic agent during lungfish evolution.

Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution

TLDR
It is found that the olfactory region appears to be more highly plastic than the hindbrain, and undergoes significant elongation in several taxa, while the semicircular canals covary as an integrated module, the utriculus and sacculus of the inner ear instead vary independently of each other.

Estuarine fish and tetrapod evolution: insights from a Late Devonian (Famennian) Gondwanan estuarine lake and a southern African Holocene equivalent

TLDR
Correlation of tetrapods (and elpistostegids) with fish nursery areas in the Late Devonian lends strong support to this hypothesis, suggesting that adaptations permitting improved access to the abundant juvenile fish within the littoral zone of estuarine lakes and continental water bodies may have been pivotal in the evolution of Tetrapods.

A new dipnoan genus from the Middle Devonian of Huize, Yunnan, China

TLDR
As the ninth Devonian lungfish genus from China, the new taxon displays a novel schema of lungfish dentition and increases the diversity of early lungfishes.

Earliest Carboniferous tetrapod and arthropod faunas from Scotland populate Romer's Gap

TLDR
It is concluded that the gap in the fossil record has been an artifact of collection failure and a series of discoveries of Tournaisian-age localities in Scotland that have yielded a wealth of new tetrapod and arthropod fossils.

Lungfish diversity in Romer's Gap: reaction to the end‐Devonian extinction

Romer's Gap, the interval following the end‐Devonian extinction event, has been described as a post‐extinction trough for vertebrates. It is a time roughly equivalent to the Tournaisian stage of the

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

An Exceptionally Preserved Transitional Lungfish from the Lower Permian of Nebraska, USA, and the Origin of Modern Lungfishes

TLDR
Morphology of the skull, hyoid arch, and pectoral girdle suggests a deviation in feeding mechanics from that of Devonian lungfishing towards the more dynamic gape cycle and more effective buccal pumping seen in modern lungfishes.

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 new species of long‐snouted lungfish from the Late Devonian of Australia, and its functional and biogeographical implications

TLDR
Morphological comparison and a cladistic analysis place Rhinodipterus crown-ward of all other Gogo lungfishes and closely related to Oervigia, Andreyevichthys and Orlovichthys.

TLDR
Ctenodus is the longest-surviving genus of lungfish from the carboniferous, and the only one to cross the Lower–Upper Carboniferous boundary, and five species span the period, with species correlated to stage.
