PROBOSCIDEAN INNOMINATE (FOSSILIZED ELEPHANT OR MAMMOTH PELVIS): IDENTIFICATION
Large fossilized partial pelvis, specifically an innominate bone comprising the ilium, ischium, and pubis, likely from a member of the Order Proboscidea. The specimen exhibits a broad, flared iliac blade and a deep acetabulum (hip socket). The mineralization suggests a transition from Late Pleistocene sub-fossilization to full permineralization, displaying a dark, ferruginous patina common in river-dredged or bog-recovered specimens.
Compare with other fossils in the archive: Fossilized Vertebra/Bone Fragment (Possibly Cetacean or other large mammal), Trilobite - Drotops megalomanicus (Devonian, Ma'der Basin, Morocco) 11cm, Prepared, Polished Devonian Goniatite Fossil.

Meaning Through Time

Evidence of extinction events and mammalian evolution.
GEOLOGICAL PERIOD
Proboscideans such as Mammuthus primigenius (Woolly Mammoth) and Mammut americanum (American Mastodon) dominated the Holarctic landscape during the Pleistocene epoch, approximately 2.5 million to 11,700 years ago. Pelvic elements of this scale are typically recovered from high-energy alluvial

deposits or anaerobic peat bogs, which preserve the dense cortical bone structure through mineral replacement.
SCARCITY
Scarce · 6/10 estimated rarity
This is a qualitative collection score, not a measured survival count, market percentile or proof of authenticity.
Visual assessment
Photographs alone cannot establish authenticity. The following analysis notes have not been independently verified; references to a match or confirmation are interpretations, not documentary evidence.
- Scale and anatomical complexity are difficult to replicate convincingly in cast resin
- Visible cancellous bone structure is consistent with genuine large mammal fossils
- Surface pitting and wear patterns align with fluvial deposition
ANALYSIS NOTES
AI-assisted notes based on the photographs and supplied context. These are interpretations, not an examination by a human specialist or proof of authenticity.
Identification of the bone as a Proboscidean pelvis is highly certain due to morphological scale; however, specific genus (Mammoth vs. Mastodon) requires precise measurements of the iliac flaring and acetabular depth not possible from a single photo.
OBSERVATIONS & INTERPRETATIONS
- 1Anatomical match for a Proboscidean innominate bone (acetabulum and ilium profile)
- 2Significant mineralization indicated by the dark coloration and light reflectivity
- 3Scale exceeds any modern terrestrial mammal except the elephant
- 4Preparation style (mounted on a modern block) is common for high-end natural history decor
UNCERTAINTIES
- •Heavy consolidation or restoration may hide cracks or composite parts
- •Lack of 'matrix' (original rock) makes locality identification solely reliant on bone coloration
WHAT WOULD IMPROVE CERTAINTY
- →Perform a UV light scan to check for non-fluorescent patches indicating epoxy restoration
- →Check for a 'tink' resonance when tapped, confirming mineral replacement versus more modern bone
- →Verify locality (e.g., North Sea dredging vs. Siberian permafrost) to ensure legal compliance regarding international trade
COLLECTOR GLOSSARY (3 terms)
- Innominate
- The large bone forming the side of the pelvis, composed of the fused ilium, ischium, and pubis.
- Acetabulum
- The cup-shaped socket in the pelvis where the head of the femur sits.
- Consolidation
- The process of applying stabilizing resins to fragile fossils to prevent crumbling or delamination.
Condition & estimated grade
A visual condition estimate. This is not a professional grading certificate.
Condition
The specimen is incomplete, lacking the sagittal symphysis and the opposing half of the pelvis. Visible stabilization or consolidation resins appear to have been applied to the thinning edges of the ilium to prevent delamination.
Weight & feel
Estimated weight between 25 kg and 45 kg, suggesting a dense, mineral-replaced bone structure rather than modern dry bone.
SPECIMEN MARKET VALUE
Estimate recorded: May 11, 2026
Estimate context (not a documented sale): Heritage Auctions (2022-2023) listed similar isolated mastodon/mammoth pelvic elements between $2,000 and $5,000 depending on state of preservation.
Who buys this
Interior designers specializing in high-end naturalism and serious natural history collectors seeking statement specimens.
What increases value
- •Size and visual presence of the iliac blade
- •Quality of the dark, aesthetic mineralization (patina)
- •Success of the modern minimalist mounting
What lowers value
- •Stability issues or hidden cracks in the thinner bone sections
- •Lack of specific locality data which can impact scientific/provenance value
- •Difficulties in shipping due to weight and fragility
What makes top-tier examples
- •Full articulation with the opposite pelvic half and sacrum
- •Absence of artificial filler or heavy restoration
- •Documented recovery from a historically significant site
Grade & condition
Completeness, anatomical integrity, and surface preservation quality.
