The Devonian stem-actinoterygian Cheirolepis canadensis is potentially important to understand the evolution of the dermal skeleton of osteichthyans, but the last detailed histological study on this taxon was published more than forty years ago. Here, we present new data about the morphology and the histological structure of scales, fulcra, and fin-rays in the Devonian actinopterygian Cheirolepis canadensis through SEM and photomicroscopy. The scales have a typical palaeoniscoid organisation…

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.
New histological information on Holoptychius Agassiz, 1839 (Sarcopterygii, Porolepiformes) provides insights into the palaeoecological implications and evolution of the basal plate of the scales of osteichthyans
ABSTRACT The porolepiform Holoptychius Agassiz, 1839 from the Upper Devonian is one of the most widely found vertebrates in the Palaeozoic fossil record. Holoptychius is considered to display a more…
The dermal skeleton of the jawless vertebrate Tremataspis mammillata (Osteostraci, stem‐Gnathostomata)
TLDR
This work describes the dermal skeleton of Tremataspis mammillata and resolves debate over the homology of the basal layer, identifying it as osteogenic acellular isopedin rather than odontogenic elasmodine or metaplastic ossification of the stratum compactum of the dermis.
Modeling Scale Morphogenesis in a Devonian Chondrichthyan and Scale Growth Patterns in Crown Gnathostomes
TLDR
This study provides the first 3D virtual growth model of stem chondrichthyan scales with a Seretolepis-type morphogenesis, offering new insights into the early evolution of chondRichthyan dermal skeletons.
Life history and ossification patterns in Miguashaia bureaui reveal the early evolution of osteogenesis in coelacanths
TLDR
The first palaeohistological and skeletochronological study of Miguashaia bureaui from the Upper Devonian of Canada is presented and reveals that the poor endoskeletal ossification known in the extant Latimeria chalumnae can be traced back at least 375 million years ago.

From body scale ontogeny to species ontogeny: Histological and morphological assessment of the Late Devonian acanthodian Triazeugacanthus affinis from Miguasha, Canada
Growth series of Palaeozoic fishes are rare because of the fragility of larval and juvenile specimens owing to their weak mineralisation and the scarcity of articulated specimens. This rarity makes…
The phylogenetic origin and evolution of acellular bone in teleost fishes: insights into osteocyte function in bone metabolism
TLDR
It is found that acellular bone is a probable synapomorphy of Euteleostei, a group uniting approximately two‐thirds of teleost species, and that the main contribution of osteocytes in teleost bone is to mineral homeostasis and not to strain detection or bone remodelling, helping to clarify their role in bone physiology.
Lower Triassic (Induan) stromatolites and oolites of the Bernburg Formation revisited – microfacies and palaeoenvironment of lacustrine carbonates in Central Germany
We propose a new facies classification scheme of the cyclic lacustrine carbonates of the Bernburg Formation (Lower Triassic, Induan), with a major focus on the microbial biota and grains. Our data…
SCPP Genes and Their Relatives in Gar: Rapid Expansion of Mineralization Genes in Osteichthyans.
TLDR
It appears that many SCPP genes expanded rapidly in stem osteichthyans and in basal actinopterygians, including many newly identified P/Q-rich genes expressed in teeth and/or scales.

A Microanatomical and Histological Study of the Postcranial Dermal Skeleton in the Devonian Sarcopterygian Eusthenopteron foordi
TLDR
The characteristics of the dermal skeleton of Eusthenopteron foordi support the hypothesis that this process began early in osteichthyans, and may be related to the evolutionary trend towards a lightening of the Dermal skeleton that would improve the swimming abilities of the animal.
A microanatomical and histological study of the fin long bones of the Devonian sarcopterygian Eusthenopteron foordi
TLDR
A paleohistological study of the endoskeletal bones of the dorsal and pelvic fins shows that Eusthenopteron foordi had true long bones that grew in length and thickness through endochondral and periosteal ossification, respectively.
An enigmatic actinopterygian (Pisces: Osteichthyes) from the Upper Permian of China
TLDR
Yaomoshania minutosquama is proposed as a small-scale bearing, basal actinopterygian, different from Cheirolepis, but characterized by advanced histological characters.
Fine structural peculiarities of the pectoral fin dermoskeleton of two Brachiopterygii, Polypterus senegalus and Calamoichthys calabaricus (Pisces, Osteichthyes)
TLDR
The lack of dentin in lepidotrichia emphasizes the tendency during evolution toward the reduction of some dermoskeletal components and exemplifies ganoine deposition directly on top of the bones as in holostei scale.
Ausgangsform und Entwicklung der rhombischen Schuppen der Osteichthyes (Pisces)
Ganoid and cosmoid scales, the two types of rhombic scales within the osteichthyans, can be traced back to a primitive scale similar to the scales ofLophosteus. The primitive rhombic scale did not…
The Devonian actinopterygian Cheirolepis Agassiz
The structure of the fishes constituting the Devonian genus Cheirolepis is investigated. Articulated remains from the Scottish Old Red Sandstone and the Canadian Upper Devonian were studied and two…
Vertebral column and associated elements in dipnoans and comparison with other fishes: Development and homology
TLDR
The formation of centra, which is not homologous among vertebrate groups, is acquired independently in some lineages of placoderms, most advanced actinopterygians, and some dipnoans and rhipidistians.
Homology of fin lepidotrichia in osteichthyan fishes.
TLDR
This interpretation might indicate that the fin-fold has been lost in early digited stem-tetrapods such as Acanthostega and Ichthyostegaand elongate basal elements, but not true lepidotrichia, occur in the caudal fins of these taxa.
Major discoveries on the dermal skeleton of fossil and Recent polypteriforms: a review
TLDR
The story of the polypteriforms has revealed some of its mysteries and the discovery of isopedine between dentine and bony basal plate in the scales of living and fossil polypterid species is considered a synapomorphy of the group, and has been an important aid in discriminatingpolypterid scales from other ganoid scales.
EXOSKELETAL ULTRASCULPTURE OF EARLY VERTEBRATES
TLDR
Systematic treatment of the ultrasculpture on the exoskeleton of Palaeozoic Agnatha is given, supplemented with a discussion of the main published sources on Gnathostomata, to show relationships between thelodonts and chondrichthyans based on ultrasculPTure characteristics are much more complicated than previously discussed.
