Murtumariskia

Murtumariskia is a genus of extinct marine reptiles that lived during the Late Triassic period, approximately 230 million years ago. The genus is known from a single species, Murtumariskia kuehnei, which was discovered in the Murtumaris Formation of the Dolomites in Italy. The name Murtumariskia is derived from the Murtumaris Formation and the Greek word "riskia," meaning "dangerous," reflecting the challenging nature of the fossil's discovery.

Murtumariskia is a member of the family Erythrosuchidae, which includes other extinct marine reptiles such as Erythrosuchus and Steneosaurus. Like other erythrosuchids, Murtumariskia had a long, slender snout and a large, triangular skull. It is estimated to have been about 3 meters (10 feet) in length, making it one of the largest known marine reptiles of its time.

The fossil of Murtumariskia kuehnei consists of a partial skull and some postcranial elements, including vertebrae and limb bones. The skull is characterized by its large size and the presence of a unique, elongated nasal bone. The postcranial elements suggest that Murtumariskia had a long, slender body and relatively short limbs, which would have been well-suited for a semi-aquatic lifestyle.

The discovery of Murtumariskia provides valuable insights into the diversity and evolution of marine reptiles during the Triassic period. Its unique features and close relationship to other erythrosuchids highlight the importance of further research into these fascinating creatures.
