	abstract = {The palaeohistology of the teeth and bony skeleton of the Late Jurassic gar {\textdagger}Nhanulepisosteus mexi-canus\&nbsp;is described in detail from thin sections. The teeth are composed of a cone of orthodentine with a pulp cavity filled with parallel canals of osteodentine as variety of eusthenodont type plicidentine. These conspicu-ous histological features differentiate {\textdagger}Nhanulepisosteus\&nbsp;from the majority of extant and fossil lepisosteids. The teeth are crowned with a small apical cap of acrodine, and are surrounded by a ridged layer of enamel. The bony tissues contain star-shaped osteocytes and canaliculi of Williamson matching exactly those in living lepisosteids, other holosteans, and some basal teleosts. Although the dental histology is distinct from that of extant gar spe-cies, we consider these differences are related to eco-morphological factors, noting that this pattern of histologi-cal arrangement is also found in other fossil gar species.},

	abstract = {<p>Abstract The study of teeth of the lower jaws of Amia calva and Polypterus senegalus, with non -destructive X-ray tomography, has revealed that there are dentine folds in the tooth pulp cavity in both species. These folds are simple and present only in the base of the pulp cavity where they strengthen the fixation of teeth on the jaw. So the teeth of these two basal actinopterygian taxa have a simplexodont type of plicidentine like the extinct {\textdagger}Cheirolepis and various extant teleostean predators, whereas the extant Lepisosteids, the sister group of Amiidae, have polyplocodont plicidentine. The phylogenetic/adaptive significance of this simplexodont plicidentine is discussed.</p>
