Ant in Amber

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

Ant in 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.
