Description

This specimen is a fossilized tooth of the extinct shark species Otodus obliquus, preserved within its original sedimentary matrix. The tooth features a prominent, triangular central cusp flanked by two smaller lateral cusplets, which is a characteristic morphology for this genus from the Paleogene period. The enamel of the crown exhibits a smooth texture with a coloration ranging from light tan to beige, showing subtle longitudinal striations near the base of the lingual side. The root is thick and displays a distinct bifurcated shape, although portions of it remain embedded in the surrounding rock. The matrix itself is a light-colored, sandy limestone or phosphatic sandstone, typical of the fossiliferous deposits found in the Ouled Abdoun Basin. The tooth is oriented such that the crown points upwards from the matrix block, providing a stable base for display. Some minor natural wear or post-depositional chipping is visible along the cutting edges of the main cusp, particularly near the apex. The specimen provides a clear view of the transition between the enameloid crown and the root structure, known as the bourlette.
