Sapindopsis

	Sapindopsis ''Sapindopsis'' ("''Sapindus''-like") is an extinct form genus for leaves of the Cretaceous Period, originally considered similar to soapberry. Associated reproductive structures now suggest it was more closely related to planes and sycamores of the family Platanaceae. Description In the form generic system of paleobotany ''Sapindopsis'' is used only for leaves, which are compound with three to six leaflets. Leaflets vary in distinctness or confluence with the midrib. The venation is pinnate, eucamptodromous to brochidodromus, with percurrent tertiary veins. Distribution and species ''Sapindopsis'' was geographically widespread from Asia to North America.

It is famous for producing massive colorful rock formations in the Rocky Mountains and the Great Plains of the United States, and for preserving both dinosaur footprints and early deciduous tree leaves.

picture info	Sannine Formation The Sannine Formation, also called the Sannine Limestone, is a Cretaceous geologic formation in Lebanon. Description 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''. The pythonomorphs '' Pontosaurus, Eupodophis'' and probably '' Aphanizocnemus'' are known from the formation. Insects are also known from compression fossils, including those of a dragonfly, enigmatic pond-skater like insect '' Chresmoda.'' and a mesoblattinid cockroach.P. Vršanský and E.
