In Somalia it is known from the Late Jurassic period in the Conca di El Mao and Gerdes el Abid (Lugh series) formations. In Ethiopia, it is known from the Late Jurassic Mugher Mudstone. Lastly for the Late Jurassic, it is known from the Aliança Formation in Brazil. In the Early Cretaceous of Tunsinia, remains have been found in the Douiret Formation. == Description ==
