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: Trilobite - Drotops megalomanicus (Devonian, Ma'der Basin, Morocco) 11cm, Prepared, Fossil Fish Positive/Negative - Vinctifer comptoni (Cretaceous, Santana Formation, Brazil), Megalodon Tooth - Otodus megalodon (Miocene to Pliocene).

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 ...
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.

CommonLegendary

Genuinely harder to find. Perhaps only dozens come to market annually. Collectors actively watch for these pieces.

Rarity 6/10. Curiosa currently catalogues 2 fossils items at rarity 6 or higher.

Typical Characteristics

  • Dozens per year at market
  • Documented provenance valued
  • Active collector pursuit

Confidence Factors

  • 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
How does authenticity detection work?

PALEONTOLOGIST'S TAKE

Paleontology Specialist

Fossil Expert

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.

KEY EVIDENCE

  • 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

CONDITION & GRADE

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

Updated: May 11, 2026

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.
