Amber Inclusion (Invertebrate Fragment)
Insecta indet. (cf. fragmented cuticle remains) • Body fossil preserved as an amber inclusion
Geological Period
Paleogene (Eocene)
Estimated Age
33 to 56 million years
Preservation Type
Three-dimensional organic preservation trapped in fossilized tree resin (amber)
Condition Assessment
Fair; the inclusion is heavily degraded, fragmented, and partially weathered or polished away at the surface, limiting high-resolution anatomical study
Taxonomic Classification
Phylum Arthropoda, Subphylum Hexapoda, Class Insecta (Order and Family indeterminate due to fragmentation)
Morphological Description
The specimen reveals highly fragmented, dark-brown to golden cuticular remains embedded within transparent resin. Diagnostic anatomical features are largely obscured, showing only irregular sclerotized plates and setal remnants near the surface.
Rock Matrix
Fossilized tree resin (amber/succinite matrix) with smooth, polished exterior surfaces lacking a traditional mineral rock matrix
Formation & Location
Baltic region (Baltic Amber) or Dominican Republic amber-bearing deposits
Size & Dimensions
The inclusion spans approximately 2 to 4 millimeters across within a larger polished amber cabochon
Value & Rarity
Estimated Market Value
$10 - $30
Auction Estimate
$15 - $40
Rarity Assessment
Common, as poorly preserved insect fragments in amber are frequently encountered
Scientific Significance
Provides limited insight into Eocene forest floor microhabitats and taphonomic processes affecting soft-bodied arthropods in resin
Preparation Recommendations
Store in a temperature-controlled environment away from direct UV light and extreme heat to prevent oxidation and crazing of the amber matrix
Notable Features
The specimen exhibits surface exposure of the internal organic remains, causing metallic-looking sheen on the exposed cuticular plates
