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

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

Life history and ossification patterns in Miguashaia bureaui reveal the early evolution of osteogenesis in coelacanths

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

Retention of fish-like odontode overgrowth in Permian tetrapod dentition supports outside-in theory of tooth origins

It is shown that, unlike the well-known one-to-one replacement patterns of marginal dentition, the palatal dentition of the early Permian tetrapods, including the dissorophoid amphibian Cacops and the early reptile Captorhinus, is overgrown by a new layer of bone to which the newest teeth are then attached.

occur in the continental upper Permian successions of European Russia. Due to their abundance and character­ istic morphology, they have been used as index fossils for biostratigraphic zonation

The phylogenetic origin and evolution of acellular bone in teleost fishes: insights into osteocyte function in bone metabolism

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.

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

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

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

Yaomoshania minutosquama is proposed as a small-scale bearing, basal actinopterygian, different from Cheirolepis, but characterized by advanced histological characters.

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.

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

Vertebral column and associated elements in dipnoans and comparison with other fishes: Development and homology

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.

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.

EXOSKELETAL ULTRASCULPTURE OF EARLY VERTEBRATES

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.

Microstructure and Growth of the Dermal Skeleton in Fossil Actinopterygian Fishes: Birgeria and Scanilepis

The histology of the dermal skeleton in Scanilepis does not support the assumption that this form is more closely related to Polypterus than other palaeonisciforms, and remarks are given on the structure of acrodin and ganoin as revealed by SEM study.
