"Anuran fossils are extremely rare in Morocco. All known specimens discovered to date belong to the Middle Miocene-Holocene periods. These fossils have been recovered from ten distinct deposits located across various regions of the Kingdom. Due to their scattered distribution, it is not possible to trace the evolutionary development of Anurans within a single area."
