Charentese amber

Charentese amber is a type of amber that is found in sediments in the Charente-Maritime area of France. It is believed to be from the Cretaceous period, which lasted from approximately 145 to 66 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. Charentese amber is also known for containing rare fossil insects like Jacobsoniidae beetle.[2] It is a valuable resource for paleontologists and other scientists studying the biodiversity of ancient ecosystems, as well as for those in the jewelry and art industries.[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.[4]
