Non-fossil Slag/Glass
Identified as industrial slag or glass waste; no biological species • Pseudofossil (Anthrogenic material)
Geological Period
Holocene (Anthropocene)
Estimated Age
Recent (0-150 years)
Preservation Type
Not applicable (Not a preserved organism)
Condition Assessment
Fair (as an object); show sharp fractures and surface pitting.
Taxonomic Classification
Non-biological; Amorphous Silicon Dioxide with impurities
Morphological Description
Amorphous, conchoidal fracturing on edges, presence of spherical internal vesicles (gas bubbles) visible on the surface, and a waxy to vitreous luster. Lacks bilateral symmetry, skeletal structure, or biological ornamentation.
Rock Matrix
Glassy/vitreous matrix with potential metallic or mineral inclusions and air-bubble voids.
Formation & Location
Found globally in areas with previous industrial activity, foundries, or historic glass production sites.
Size & Dimensions
Approximately 8-10 cm in diameter; consistent with industrial debris.
Value & Rarity
Estimated Market Value
$0 - $5 USD
Auction Estimate
$0 USD
Rarity Assessment
Common; industrial byproduct and man-made waste are frequently mistaken for fossils or meteorites.
Scientific Significance
Low paleontological significance; however, it serves as an example of a 'pseudofossil' that mimics biological shapes or geological minerals.
Preparation Recommendations
No special paleontological preparation required. Can be cleaned with soap and water to remove surface dirt.
Notable Features
The most notable features are the distinct vesicles (bubbles) and the conchoidal (shell-like) fracture patterns across the surface, which are diagnostic of glass or slag rather than biological petrifaction.
