Amber Inclusion Fossil
Indeterminate insect/invertebrate inclusion, cf. Diptera or Hymenoptera • Body fossil and amber inclusion (fossilized tree resin containing biological matter)

Geological Period
Cretaceous to Paleogene (typically associated with mid-Cretaceous or Eocene deposits)
Estimated Age
40 to 100 million years
Preservation Type
Three-dimensional amber preservation (fossilization via polymerisation of plant resin, preserving soft tissues and fine structures in exquisite detail)
Condition Assessment
Fair to Good. The amber chunk shows natural surface weathering and oxidation on the exterior, but internal transparency allows partial view of the embedded inclusion.
Taxonomic Classification
Phylum Arthropoda, Class Insecta (or other small invertebrates)
Morphological Description
The specimen exhibits a translucent to deep amber-brown resin matrix containing small, poorly defined organic inclusions with visible contours, suggestive of an insect exoskeleton or micro-organism trapped within the hardened resin.
Rock Matrix
Fossilized tree resin (amber) with weathered outer crust and minor surface oxidation
Formation & Location
Baltic amber deposits, Dominican Republic, or Burmese (Kachin) amber mines
Size & Dimensions
Approximately 1 to 3 centimeters across, consistent with typical small to medium amber chunks containing micro-inclusions
Value & Rarity
Estimated Market Value
$50 - $200 USD
Auction Estimate
$40 - $150 USD
Rarity Assessment
Common to Uncommon, depending on the exact taxonomic identification and clarity of the inclusion
Scientific Significance
Amber inclusions provide exceptional insights into ancient terrestrial ecosystems, revealing preserved behavior, soft anatomy, micro-parasites, and paleoclimate data that are entirely lost in standard rock-matrix fossils.
Preparation Recommendations
Gentle mechanical cleaning with soft brushes, followed by stabilization using professional conservation-grade acrylic or polyolefin resins if fracturing occurs. Store in UV-protected, low-humidity containers to prevent crazing and oxidation.
Notable Features
Contains a distinct trapped amber inclusion with golden-brown tones contrasting against the darker, weathered exterior matrix.
