Ant in Amber
Formicidae indet. (cf. Formica or Tapinoma) • Body fossil, insect inclusion in fossilized tree resin (amber)

Geological Period
Paleogene (Eocene epoch)
Estimated Age
33 to 56 million years old
Preservation Type
Three-dimensional exceptional preservation via entrapment in fossilized tree resin (amber), preventing decay and capturing fine cuticular microstructures.
Condition Assessment
Good to Very Good. The insect is mostly complete and clearly visible from multiple angles, though slight occlusion from internal resin impurities or surface micro-scratches is present.
Taxonomic Classification
Phylum: Arthropoda, Class: Insecta, Order: Hymenoptera, Family: Formicidae
Morphological Description
The specimen exhibits a well-preserved ant body enclosed within a translucent amber matrix. Visible anatomical features include segmented antennae, compound eyes, the mesosoma, petiole, and gaster. The exoskeleton shows sharp structural details with a dark brown to black coloration contrasting against the warm yellow-orange amber.
Rock Matrix
Transparent to translucent fossilized amber (resinite) with warm honey-yellow to brownish tones, polished smooth with minor surface scuffs and reflections.
Formation & Location
Baltic region (Baltic Amber) or Dominican Republic (Dominican Amber), representing tropical to subtropical ancient forest resin deposits.
Size & Dimensions
The amber piece is approximately 3 to 4 cm in length, with the enclosed ant measuring roughly 4 to 6 mm, which is typical for worker ants of this geological epoch.
Value & Rarity
Estimated Market Value
$50 - $150 USD
Auction Estimate
$40 - $120 USD
Rarity Assessment
Common. Ant inclusions are among the most frequently encountered insect fossils in Baltic and Dominican amber.
Scientific Significance
Amber inclusions provide exceptional snapshots of ancient forest ecosystems, offering insights into early Cenozoic insect evolution, behavior, morphology, and paleoenvironments.
Preparation Recommendations
Store in a temperature-stable, low-humidity environment away from direct UV light to prevent degradation, crazing, or oxidation of the amber matrix. Clean gently with a soft microfiber cloth if necessary.
Notable Features
Clear visibility of the ant's appendages and segmented body suspended in high-clarity amber, making it an excellent educational and display specimen.
