Description from the seller
Upper front tooth belonging to Isurus oxyrinchus (shortfin mako shark), order Lamniformes, family Lamnidae. This tooth, measuring 50 mm, is well preserved and morphologically complete, displaying the characteristic structural features of the species: smooth, pointed, and non-serrated crown, tapered shape with a slight distal curvature, with a compact and porous root.
The crown exhibits a shiny glazed coating with uniform ivory tones, indicating high mineralization and tissue integrity. The root, slightly arched, shows a light beige coloration with clearly visible porosity, indicative of a natural unaltered origin.
The tooth can be functionally classified as a penetration tool and weapon. Its sharp and symmetrical shape makes it particularly suitable for the diet of the mako shark, which consists of highly mobile pelagic bony fish such as tunas (Thunnus spp.), mackerels (Scomber spp.), and swordfish (Xiphias gladius). The extreme speed of this predator (over 70 km/h) requires an effective attack strategy: the front teeth, like this one, act as true natural projectiles, designed to maximize penetration with minimal friction.
