Deltasaurus is an extinct genus of Carnian temnospondyl amphibian of the Rhytidosteidae family.
Taxonomy
The genus was erected in 1965 by John W. Cosgriff, when describing two new species discovered northwest Australia. The author recognised an alliance with other genera that had been uncovered in Africa, and proposed their arrangement to a new superfamily, Rhytidosteoidea.
It is the most common animal fossil of the Blina Shale, a fossil deposit at the eastern end of the Erskine Range in the Kimberley region of Western Australia. A specimen has also been collected from the Knocklofty Sandstone deposit in Tasmania.
The genus places two fossil taxa, Deltasaurus kimberleyensis, the type species which grew to around 90 centimetres in length, and Deltasaurus pustulatus, also described by Cosgriff in 1965.
It had four limbs and a tail, and numerous tiny teeth. It is thought to have been a predator of fish.
