1846 METOPOSAURUS OUAZZOUI / DUTUITOSAURUS Upper Triassic, Carnian (216-228 million years) Argana Basin, Morocco 41 x 32 cm Provenance: Swiss private collection Certificate: Comes with a certificate of authenticity from the “GeowissenschaftlichemAteliers“. In the 1960s, remains of a new amphibian species were discovered in the Argana Basin in Morocco. The Dutuitosaurus, named after the palaeontologist Jean-Michel Dutuit, lived on earth and in water about 220 million years ago in the Late Triassic. It has similarities with the traditional Metoposaurus and until the 1990s it was also called Metoposaurus ouazzoui. Differences were then discovered in the spaces between the skulls and Dutuitosau- rus was recognised as a separate genus from 1993. This beautiful fossilised skull is perfectly preserved with less than 1% restoration. An incredible relic of the early periods when amphibians ruled the earth.

The most striking external feature of the woolly giant is its two tusks in the upper jaw. In contrast to elephant species still living today, the tusks in the adult mammoth are curved upward in a spiral pattern. The tips point inwards and are thus directed towards each other. Besides presenting dominance in mating or ritual combat or as a warning signal for food competitors, the tusks were often used for sear- ching for food. The presented here tusk is in a fantastic original condition, showing beautiful color and textures. It comes with a custom built contemporary stand.
