Discovery of Late Cretaceous amber from Guangzhou, South China

Abstract

Cretaceous amber plays a crucial role in comprehending the origin and early evolution of terrestrial life, as well as understanding paleoclimate and paleoecology during the Late Mesozoic, especially the Cretaceous Terrestrial Revolution. Amber outcrops from the Cretaceous period are to date more abundant in the Northern Hemisphere than in the Southern one and are primarily distributed within an interval of approximately 54 million years, spanning from the Barremian to the Campanian (Delclòs et al., 2023). These outcrops are known for containing amber exceptionally rich in bioinclusions, as seen in locations such as Kachin in Myanmar (Grimaldi et al., 2002) and Lebanon (Maksoud et al., 2022).
