	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.},
