Genuine Isurus Oxyrinchus Anterior Tooth - Mako shark...

Elegant specimen of a tooth from Isurus oxyrinchus with a gleaming enamel and intact root — This specimen presents an upper anterior tooth of Isurus oxyrinchus, commonly known as the shortfin mako shark, belonging to the order Lamniformes and the family Lamnidae. The tooth, measuring 50 mm in length, is magnificently preserved and morphologically complete, illustrating in exemplary fashion the distinctive features of this species. The crown is smooth, pointed, and dentition-free of serrations, with a tapered shape and a slight distal curvature that highlights its natural elegance. The root is compact and porous, maintaining its structural integrity. The crown exhibits an enamel coating of exceptional luster, characterized by homogeneous ivory tones that attest to high mineralization and excellent condition of the original tissue. The root, with its delicate curvature, shows a light beige coloration and clearly visible porosity, elements that confirm its natural origin and the absence of alterations. Every detail, from the sharp tip to the base, is well defined, making this tooth a subject of study and admiration. Functionally, a tooth like this can be classified as a highly specialized penetrating and injuring instrument. Its sharp, symmetrical shape was perfectly adapted to the diet of the mako shark, which includes extremely fast pelagic bony fish such as tunas (Thunnus spp.), mackerels (Scomber spp.), and swordfish (Xiphias gladius). The extraordinary speed of this predator, which can exceed 70 km/h, made an efficient hunting strategy essential. The anterior teeth, like the specimen presented here, acted as true natural projectiles, designed to maximize penetration into prey with minimal friction, ensuring maximum effectiveness in capture. The origin from Madagascar, although the data 'Era/Formation: 2025' is clearly a dating error and should be interpreted as a modern or sub-fossil tooth from recent deposits, adds an exotic touch to this piece. This specimen represents a fascinating testimony to the evolution and predatory adaptation of one of the most formidable marine hunters. An object of great interest for collectors, marine biology scholars, or simply for those who desire a unique piece of natural history as a Wunderkammer decorative element. Any minor irregularities, cavities, or color variations should be considered natural characteristics of the specimen and not defects.
