Abstract

The Eocene represents a critical period for amber formation, yet relatively few Eocene amber deposits have been documented in China. To date, only the fossiliferous Fushun amber (Liaoning Province) and the relatively less explored Maoming amber (Guangdong Province) have been described. In this study, we report Eocene amber from Longkou, Shandong Province, eastern China, and provide mineralogical Fourier Transform Infrared (FT-IR) spectroscopic characterization. This represents the first record of amber from Shandong Province. Longkou amber occurs abundantly within Eocene coal seams, offering considerable potential for future discoveries of biological inclusions.
