Diversity of Extinct and Living Actinistian Fishes (Sarcopterygii)
Environmental Biology of Fishes, 1991A total of 121 actinistian species belonging to 47 genera and 17 undetermined actinistians is reported from the literature. There are 69 valid species with fair assessment of their phylogenetic position; 21 valid species with poor assessment of their phylogenetic position; 31 actinistian incertae sedis; and 18 taxa that had been identified incorrectly ...

IV SARCOPTERYGII, Fleischflosser
2014Unter den rezenten und fossilen Fischen sind die Sarcopterygier durch fleischige Loben an den paarigen Flossen charakterisiert. Fossil gehen sie bis in das Obere Silur (vor 420 Mio. Jahren) zuruck.

Sarcopterygii and the Origin of Tetrapods
1977The affinities of land vertebrates have been discussed many times, the history of the issue in itself being an interesting subject. It is not necessary at the moment to go into details; let us only recall that the important paper of Jarvik (1942), as well as the long series of later publications by this author (e.g.

The mystery of the two‐unit skull of the Sarcopterygii: a trap for functional morphologists
Journal of Zoology, 2016AbstractThis is an analytical study which presents a rigorous biomechanical interpretation of the well known but poorly understood two‐unit skull of extantLatimeriaand extinct non‐dipnoan sarcopterygian fishes. The two units, anterior ethmosphenoid and posterior otoccipital, are hinged, dorsally, by intracranial syndesmosis between parietal and ...

Journal of Structural Biology, 2015
The extant coelacanth Latimeria is a sarcopterygian predatory fish with caniniform teeth on its upper and lower jaws. The teeth are constituted of a cone of dentine with an apical cap of enamel, and they are fixed to the osseous component of the jaws by an attachment bone.

Ultrastructural data on the scales of the dipnoan Protoptems annectens (Sarcopterygii, Osteichthyes)
Journal of Zoology, 1988The structure and the mineralization of the scales of the living dipnoan (lungfish) Protoptems annectens have been investigated by transmission electron microscopy (TEM). The thin and imbricated scales are composed of two layers: the squamulae and the basal plate.
