Abstract

Cretaceous amber plays a key role in understanding the evolution of Late Mesozoic biotas and the changes in palaeoclimate and palaeoenvironment. This study reports Late Cretaceous amber from the Taipinglinchang Formation in Jiayin County, Heilongjiang Province, northeastern China, and presents its Fourier Transform Infrared (FT-IR) spectroscopic characteristics. These ambers are small in size, relatively concentrated on the bedding horizons, and associated with abundant charcoals, reflecting that wildfire events were responsible for the formation of the amber beds. Research on this amber occurrence provides important empirical materials for investigating the resin secretion characteristics of resin-producing plants and the palaeoenvironmental conditions of the Jiayin area during the Late Cretaceous.
