A 409-million-year-old predatory fish provides unique insights into the early evolution of modern lobe-finned fishes. Crown or modern sarcopterygians (coelacanths, lungfishes, and tetrapods) differ substantially from stem sarcopterygians, such as Guiyu and Psarolepis, and a lack of transitional fossil taxa limits our understanding of the origin of the crown group. The Onychodontiformes, an enigmatic Devonian predatory fish group, seems to have characteristics of both stem and crown…

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.
Sarcopterygian Fishes, the “Lobe-Fins”
TLDR
This chapter will introduce you to groups now known exclusively from fossils such as “dagger-toothed” onychodonts and porolepiforms named so for the special pores in their scales.
The cranial endocast of the Upper Devonian dipnoan ‘Chirodipterus’ australis
TLDR
A new detailed anatomical description of the endocast of ‘Chirodipterus’ australis from the Upper Devonian Gogo Formation of Western Australia, known for exceptional 3D preservation which enables fine-scale scrutiny of endocranial anatomy, is presented, showing that it exhibits a suite of characters more typical of Lower and Middle Devonian dipnoan taxa.
A microanatomical and histological study of the scales of the Devonian sarcopterygian Miguashaia bureaui and the evolution of the squamation in coelacanths
TLDR
The scales of Miguashaia bureaui are described, revealing histological data for a Palaeozoic coelacanth in great detail and adding to the authors' knowledge on the dermal skeleton of sarcopterygians.
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.
Internal cranial anatomy of Early Triassic species of †Saurichthys (Actinopterygii: †Saurichthyiformes): implications for the phylogenetic placement of †saurichthyiforms
TLDR
The phylogenetic scheme highlights outstanding questions concerning the affinity of many early actinopterygians, such as the Paleozoic–early Mesozoic deep-bodied forms, which are largely caused by lack of endoskeletal data.
A large onychodontiform (Osteichthyes: Sarcopterygii) apex predator from the Eifelian-aged Dundee Formation of Ontario, Canada
The Devonian marine strata of southwestern Ontario, Canada, have been well documented geologically, but their vertebrate fossils are poorly studied. Here we report a new onychodontiform…
A fresh look at Cladarosymblema narrienense, a tetrapodomorph fish (Sarcopterygii: Megalichthyidae) from the Carboniferous of Australia, illuminated via X-ray tomography
TLDR
The first full, virtual cranial endocast of any tetrapodomorph fish is presented, giving insight into the early neural adaptations in this group, and further work is required to resolve megalichthyid interrelationships.
The cranial endocast of Dipnorhynchus sussmilchi (Sarcopterygii: Dipnoi) and the interrelationships of stem-group lungfishes
TLDR
The first phylogenetic analysis of Dipnoi based purely on endocast characters supports a basal placement of Dipnorhynchus within the dipnoan stem group, in agreement with recent analyses, and demonstrates the value of endocasts characters for inferring phylogenetic relationships.
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 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.
A primitive fish close to the common ancestor of tetrapods and lungfish
TLDR
Styloichthys from the Lower Devonian of China bridges the morphological gap between stem-group sarcopterygians (Psarolepis and Achoania) and basal tetrapodomorphs/basal dipnomorphs and provides information that will help in the study of the relationship of early sarcoperygians, and which will also help to resolve the tetrapods–lungfish divergence into a documented sequence of character acquisition.
The African coelacanth genome provides insights into tetrapod evolution.
TLDR
Through a phylogenomic analysis, it is concluded that the lungfish, and not the coelacanth, is the closest living relative of tetrapods.
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. These…
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.
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.
The earliest known stem-tetrapod from the Lower Devonian of China.
TLDR
The enlargement of the cerebral hemispheres and the possible presence of the pars tuberalis in this stem-tetrapod indicate that some important brain modifications related to terrestrial life had occurred at the beginning of the tetrapod evolution, much earlier than previously thought.
NEW ONYCHODONTIFORM (OSTEICHTHYES; SARCOPTERYGII) FROM THE LOWER DEVONIAN OF VICTORIA, AUSTRALIA
Abstract The Onychodontiformes is a poorly known sarcopterygian fish group, with four genera currently described, predominantly from the Middle-Late Devonian. A new onychodont, Bukkanodus jesseni n.…
The First Virtual Cranial Endocast of a Lungfish (Sarcopterygii: Dipnoi)
TLDR
This virtual cranial endocast of Rhinodipterus kimberleyensis, from the Late Devonian Gogo Formation of Australia, is one of the most derived fossil dipnoans with a well-ossified braincase and has numerous similarities to the endocasts of Chirodipteru wildungensis and Griphognathus whitei.
