As the only direct records of history evolution, it is critical to determine geological source biota-bearing fossils. Through application synchrotron-radiation micro-computed tomography (SR-µ-CT), Fourier-transformed infrared-spectroscopy (FT-IR), visual evaluation ultraviolet fluorescence (UV-VS), radiocarbon dating ( 14 C quantification), and historical sleuthing, we were able identify sort 161 (83 Baltic amber, 71 Copal 7 Kauri gum pieces) individually numbered largely mislabeled pieces East African Defaunation resin (~145 years old) copal (~390 old), as well amber (~35 million from Phyletisches Museum collection. Based on this collection, define two new species: ‡ Amphientomum knorrei Weingardt, Bock & Boudinot, sp. nov.
