4.4 cm massive tooth from Otodus obliquus

The 4.4 cm tooth of Otodus obliquus has a solid enamel that is shiny and grey-brown in colour. The two typical secondary teeth are preserved. The root has been repaired, which is clearly visible in the pictures. As one of the first true ‘giant toothed sharks’, O. obliquus is considered an important apex predator that could reach a body length of up to 9 metres. The teeth are the most common fossil of this species: they grow up to 10 cm long, have a fairly straight, triangular shape with smooth cutting edges, a solid root and a lateral secondary tooth (‘small tooth’) on each side. As an effective hunter, O. obliquus probably fed on fish and other sea creatures, using its smooth teeth to pierce its prey.
