Sannine Formation
The Sannine Formation also called the Sannine Limestone is a Cretaceous geologic formation in Lebanon. It is primarily Cenomanian in age. The formation laterally varies from east to west; the western lowland "coastal" sequence is over 2000 metres thick and primarily consists of deep water limestone and chalk, while the eastern "mountain" sequence is 500–700 metres thick and consists of shallow water limestone. Pterosaur fossils have been recovered from the formation, including those of Mimodactylus and Microtuban. Insects are also known from compression fossils, including those of dragonflies. Enigmatic pond-skater like Chresmoda. A cockroach. And angiosperm Sapindopsis. Numerous species of fossil fish are also known.
