Descrizione
Baltic amber with insects and inclusions 20 mm. (7)
Eocene (50 - 35 Ma) Baltic Sea

Baltic amber from the Eocene era (35 to 50 million years ago), Baltic Amber is an organic substance, a “fossil resin” produced by pine trees which grew in Northern Europe - from southern regions of the present day Scandinavia and nearby regions of the bed of the Baltic Sea. The climate became warmer and trees started to exude big amounts of resin. Scientists say that amber is a fossil pine resin from this region that has achieved a stable state through oxidation.

The structure of Baltic amber (succinite) is complex. It is not a polymer, because it is not composed of a repeating pattern of mers of the same type. Rather it has a macromolecular structure arranged in a crosslinked network, in which the pores (free spaces) are filled by components of molecular structure (e.g. by mono- and sesquiterpenes). Thus the chemical structure of the amber may be described as a supramolecule.[7] The structure makes the amber denser, harder and more resistant to external factors. It also makes possible good preservation of plant and animal inclusions
