Amber-encased Scorpion
Scorpiones indet. cf. fossil family (likely Chactidae or Buthidae) • Body fossil, amber inclusion, invertebrate
Geological Period
Neogene (Miocene)
Estimated Age
15 to 25 million years
Preservation Type
Exceptional three-dimensional amber preservation (fossil resin inclusion) preserving delicate cuticular structures without compression
Condition Assessment
Excellent, highly complete, fully articulated with minimal micro-fractures in the surrounding amber matrix
Taxonomic Classification
Phylum Arthropoda, Subphylum Chelicerata, Class Arachnida, Order Scorpiones
Morphological Description
The specimen displays complete articulation showing the prosoma (cephalothorax), mesosoma, metasoma (tail), and telson (stinger). All four pairs of walking legs, pedipalps with large chelae (claws), and segmental plates of the abdomen are clearly visible in dorsal/ventral orientation.
Rock Matrix
Transparent to translucent amber (fossilized tree resin) with a dark reddish-brown to amber hue
Formation & Location
Dominican Republic (Cordillera Septentrional) or Mexican (Chiapas) amber mines
Size & Dimensions
Approximately 3 to 4 cm in total length for the inclusion, fitting within a polished amber gemstone measuring roughly 5 to 7 cm
Value & Rarity
Estimated Market Value
$1,500 - $3,500
Auction Estimate
$2,000 - $4,000
Rarity Assessment
Rare, as intact scorpions in high-quality amber are exceptionally uncommon compared to smaller insects
Scientific Significance
Provides extraordinary morphological data on Miocene arachnids, offering insights into tropical forest paleoecology, evolution, and ancient arthropod behavior
Preparation Recommendations
Professional cutting and polishing of the amber gemstone to enhance viewing angles; store away from direct UV light and extreme heat to prevent oxidation and crazing
Notable Features
Remarkable 3D preservation showing fine details of the pedipalps, eye tubercles, pectines, and the complete segmented tail terminating in the stinger
