Amber
Amber is fossilized tree resin, distinct from sap or pitch. It serves as a critical medium for preserving fossils, particularly insects and other small organisms, providing insights into ancient ecosystems.
Recent Discoveries & Evolutionary Context
- Oldest Amber Discovery Redefines Plant Resin Defense Evolution
- Recent findings challenge previous timelines for the evolution of plant resin as a defense mechanism.
- See Oldest Amber Discovery Redefines Plant Resin Defense Evolution for detailed analysis of the discovery.
- The discovery suggests plant resin defense mechanisms evolved significantly earlier than previously thought, reshaping our understanding of plant-evolution and co-evolution with arthropods.

Key Properties
- Composition: Primarily composed of terpenes and other organic compounds that polymerize over millions of years.
- Color: Typically golden-yellow, but can range from red to black depending on impurities and oxidation.
- Hardness: Relatively soft compared to gemstones, requiring careful handling.
- Flammability: Burns with a resinous smell; historically used as a fuel source.
Cultural & Scientific Significance
- Paleontology: Provides a window into Cenozoic and Mesozoic eras, preserving soft tissues rarely found in rock records.
- Jewelry: Valued for its warmth and color; often used in jewelry and art.
- Medicine: Historically used in traditional medicine; modern research explores its antimicrobial properties.
- Pop Culture: Famously depicted in Jurassic Park as the medium for extracting dinosaur DNA.
