Amber is a fossilized form of tree resin, formed when sticky exudations from ancient trees underwent polymerization and subsequent mineralization over millions of years. This natural process effectively encases the biological materials found within the resin, preserving specimens and offering crucial insights into the paleoenvironments and biodiversity of past eras. Chemically, the material is composed of complex organic polymers, primarily derived from terpenes, which gives it a stable, durable structure. Due to its preservation capacity, amber is highly valued in paleontology, serving as a direct window into deep time life.
