It dates to the late Albian to early Cenomanian stages of the mid-Cretaceous, around 100 million years ago.
[1] The amber is known for its high quality and preservation of inclusions, such as insects, plant debris and other organisms.
[2] It is a valuable resource for paleontologists and other scientists studying the biodiversity of ancient ecosystems.
[3] The amber is often, but not always, opaque, requiring the usage of X-ray microtomography in order to observe specimens.
[4][3] Charentese amber has unique geochemical properties such as high content of succinic acid, and a unique ratio of stable isotopes C13/C12, which make it a valuable tool for geochemical and climatic reconstructions of Cretaceous period.
