Otudus is a genus belonging to the shark group known as mackerel sharks. It reigned the seas during the Paleocene and the Eocene (60-45 million years ago). It is a quite dominant species in the phosphate quarries in this sector of Morocco. This species has only been described via its teeth and vertebrae. As all the Elasmobranchii, the skeleton has a cartilaginous non-osseous nature, what makes difficult its fossilization process. . The teeth of this shark are large with a triangular crown, smooth cutting edges, and visible cusps on the roots.

The fossils of this huge shark indicate that it must have been an incredible marine macro-predator. Its length has been estimated between 9 and 12 m (30-40 ft).

A physical certificate of authenticity is provided free of charge with every fossil we sell. This is our lifetime guarantee.
