Earth:Charentese amber
Charentese amber is a type of amber that is found in sediments in the Charente-Maritime area of France . It dates to the late Albian to early Cenomanian stages of the mid-Cretaceous, around 100 million years ago. Charentese amber has been known since the early 19th century and was originally referred to as succin, succinic resin, or retinasphalt.[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.[5]
