Microtuban is known only from a partially preserved skeleton lacking the skull, holotype SMNK PAL 6595. It was acquired from a local fossil dealer by the Staatliches Museum für Naturkunde Karlsruhe and was, as can be deduced from the qualities of the stone matrix, collected in the locality of Hjoûla in a marine layer of the Sannine Formation, dating to the early Cenomanian stage of the Late Cretaceous, about 99.6-96 million years ago. The fossil dealer however, indicated it came from a quarry at nearby Hâqel. Regardless, it is only the second pterosaur fossil found in Lebanon and a rare example of a pterosaur from the African continental plate, to which the area in Cretaceous times belonged. In this period the site was located hundreds of miles from the mainland coastline.[1]
