Mimodactylus libanensis: A new species of Istiodactyliform Pterosaur from the Late Cretaceous Hjoûla Lagerstätte of Lebanon.
[sciencythoughts.blogspot.com]
The Mesozoic Vertebrate palaeontology of Africa and Arabia is still largely veiled in mystery. Except for South Africa, where systematic studies, mainly in Triassic and Lower Jurassic continental deposits have provided a comparatively diverse Vertebrate fauna, information about the biota that lived during most of the Mesozoic Era in this region is extremely limited. This is particularly true for Pterosaurs, an extinct group of flying reptiles that includes the major powered flying Vertebrates for almost 160 million years. The main African records of this group are restricted to isolated elements from the Jurassic deposits of Tendaguru, Tanzania, the Late Cretaceous Kem Kem Beds and Ouled Abdoun deposits of Morocco. The most complete Pterosaur specimens from the Afro-Arabian region have been recovered from the Cenomanian (100.5-93.9 million year old) marine deposits of Lebanon. The first specimen was a partial left forelimb of a relatively small unnamed Ornithocheiroid Pterosaur from Hâqel Lagerstätte and the second a crushed skeleton formed mainly by two wings and the shoulder girdle of the Azhdarchoid Microtuban altivolans, from the coeval (equivalent in time) Hjoûla Lagerstätte.
