• Bitterfeld amber occurs in the "Bernsteinschluff" Horizon, i.e. a part of the Upper "Bitterfelder Glimmersand" in the upper part of the Cottbus Formation. Detailed biostratigraphic investigations favor an uppermost Chattian age for the unit. Originally assigned a Miocene age, and then thought to be redeposited Baltic amber. The chemical composition of Bitterfeld amber is distinct from true Baltic amber (e.g., Sodhi et al., 2013). Hydrogen isotopes indicate that Baltic and Bitterfeld ambers have distinct geographic sources, but carbon isotopes and insects suggest Baltic and Bitterfeld ambers are coeval in age (Wolfe et al., 2016).
