Not a fossil (Igneous rock fragment / Granite pebble)
N/A (Granite / Granitic rock) • None (Inorganic geological specimen)
Geological Period
Precambrian to Phanerozoic (dependent on regional intrusive events)
Estimated Age
Variable (often hundreds of millions to billions of years for crystalline basement rocks)
Preservation Type
N/A (Crystalline igneous rock formation, not fossilized organic material)
Condition Assessment
Good (natural weathered pebble with smooth water-worn or transported edges)
Taxonomic Classification
N/A (Igneous rock, Plutonic, Felsic)
Morphological Description
Small, sub-angular to sub-rounded pebble showing interlocking crystalline texture with visible grains of quartz, pinkish potassium feldspar, and dark biotite or hornblende minerals.
Rock Matrix
Granitic intrusive rock consisting primarily of quartz, feldspar, and accessory minerals
Formation & Location
Found globally in glacial tills, river gravels, and weathered outcroppings of continental shields and mountain belts
Size & Dimensions
Approximately 1.5 cm by 1.0 cm by 0.8 cm
Value & Rarity
Estimated Market Value
Zero (common geological rock sample with no commercial value)
Auction Estimate
N/A
Rarity Assessment
Common (ubiquitous geological formation)
Scientific Significance
Illustrates basic petrological concepts of intrusive igneous crystallization and mineral composition, but holds no paleontological significance.
Preparation Recommendations
No preparation or conservation required; store as a standard mineral or rock sample.
Notable Features
Classic pinkish potassium feldspar grains characteristic of standard granitic rocks, frequently mistaken by novices for bone fragments or fossilized teeth due to its size and color.
