基　　金：the project"The Study of the Fossil Insects and their Outcrops in Lebanon:Geology of the Outcrops-Historical and Biodiversity Evolution",which received a grant by the Lebanese University(to DA and RG)

摘　　要：Reports of amber predating the Lower Cretaceous are unusual and scarce; they mostly refer to amber pieces of millimetric dimension. In the present study, we report the discovery of 10 new outcrops of Jurassic amber in Lebanon. Some of these had large centimetric-sized pieces of amber. The new localities are described, amber is characterized, and its infrared spectra given. Although the new Jurassic amber yielded to date no more than fungal inclusions, this material is significant and promising. The discovery, of several Jurassic outcrops provides crucial information on the prevailing paleoenvironment of that time.Reports of amber predating the Lower Cretaceous are unusual and scarce; they mostly refer to amber pieces of millimetric dimension.
