Presence of plicidentine in the oral teeth of the coelacanth Latimeria chalumnae Smith 1939 (Sarcopterygii; Actinistia)

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.

The mystery of the two‐unit skull of the Sarcopterygii: a trap for functional morphologists

Journal of Zoology, 2016
AbstractThis 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 ...

Ultrastructural data on the scales of the dipnoan Protoptems annectens (Sarcopterygii, Osteichthyes)

Journal of Zoology, 1988
The 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.

The oldest know stegocephallian (sarcopterygii: temnospondyli) from spain

2006
More data are provided on the recently described temnopondyl Iberospondylus schultzei from the Upper Carboniferous (Stephanian C) of the Spanish PuertollanoBasin. It represents the only know occurence of a Paleozoic stegocephalian in a Spanish basin. This taxon appears to be more closely related to eryopoids and dissorophoids than to edopoids, as shown
