Figure 1 in Histological characteristics of lower jaw bones and oral teeth of the short nose gar, Lepisosteus platostomus Rafinesque, 1820 (Lepisosteidae)

Figure 1. – Lepisosteus platostomus. Tomographic image of a fang (black asterisk), and a mid-sized caniniform teeth (white asterisk) in the anterior part of the left lower jaw. The tridimensional reconstruction of the dentary bone and teeth shows three folds in the internal wall of the fang (arrows), which occupy two thirds of the pulp cavity. The space indicated by arrows between the narrow walls of each fold corresponds to external area of the tooth due to the synchronized folding of both the dentine and the collar enamel. The pulp cavity of the second tooth also shows two folds (arrowheads) along the vertical axis of the shaft. Scale bar = 500 μm. (from Germain et al., 2016: fig. 1).
