Felted / Partial Lithic Fragment (Poss. Weathered Bone Fragment)
Indeterminate vertebrate cf. Mammalia sp. • Body fossil (Incomplete), possibly a highly weathered vertebrate bone fragment or a non-biological lithic clast
Geological Period
Indeterminate (Possibly Holocene to Pleistocene context based on preservation)
Estimated Age
0.01 - 2.5 million years (Uncertain without stratigraphy)
Preservation Type
Surface weathering and possible mineralization; poor preservation quality with loss of anatomical detail.
Condition Assessment
Poor Condition - Fragmentary, abraded, and weathered with no identifiable anatomical features.
Taxonomic Classification
Phylum: Chordata, Class: Mammalia (putative identification based on texture; non-diagnostic)
Morphological Description
Irregular, sub-triangular tan-colored fragment with coarse, fibrous-looking surface texture. Lacks articulated joints, marrow cavities, or diagnostic landmarks. Shows evidence of heavy abrasion and rounding of edges.
Rock Matrix
Matrix absent; specimen is an isolated surface find with no adhering parent rock.
Formation & Location
Commonly found in alluvial deposits, riverbeds, or coastal terraces; likely geographic origin in North America or Europe.
Size & Dimensions
Approximately 3-5 cm in length (estimated from background textures); small size compared to typical megafauna limb bones.
Value & Rarity
Estimated Market Value
$1 - $10 USD
Auction Estimate
$0 - $20 USD (Typically sold as bulk study material)
Rarity Assessment
Common - Non-diagnostic weathered bone or rock fragments are frequently found in surface deposits.
Scientific Significance
Low - Due to the lack of stratigraphic context and diagnostic features, this specimen provides minimal data on evolution or paleoecology.
Preparation Recommendations
No invasive preparation needed; dry brush to clean. Store in a stable, low-humidity environment to prevent delamination.
Notable Features
Specimen exhibits a porous texture that can be tested for porosity (tongue test) to differentiate bone from silicate rock.
