Sea Turtle Skull (Modern Bone / Osteological Specimen)
Chelonia mydas (Green Sea Turtle) or Caretta caretta (Loggerhead Sea Turtle) cf. • Modern Osteological Specimen (Skeletal Remains / Vertebrate Bone)
Geological Period
Holocene / Recent (Modern)
Estimated Age
0 Million Years (Modern / Contemporary)
Preservation Type
Unfossilized Real Bone / Natural Skeleton Preparation (Osteology)
Condition Assessment
Very Good (Cleaned bone preparation, intact neurocranium and orbits, minor natural weathering/bleaching)
Taxonomic Classification
Chordata, Reptilia, Testudines, Cryptodira, Cheloniidae / Dermochelyidae
Morphological Description
Anapsid-like modified cranium with large, dorsolaterally facing orbital cavities, fused premaxillae and maxillae forming a beak-like rhampotheca support, fine vascular foramina pitting the bone surface, and a broad, solid neurocranium structure.
Rock Matrix
None (Free-standing cleaned bone specimen without matrix)
Formation & Location
Modern Marine / Coastal Environment (Contemporary origin, worldwide tropical to subtropical oceans)
Size & Dimensions
Approximately 15 - 25 cm in length, typical for a subadult to adult marine turtle skull
Value & Rarity
Estimated Market Value
$150 - $450 USD (Note: Legal trade is heavily restricted under CITES Appendix I regulations for endangered sea turtle species)
Auction Estimate
$200 - $500 USD (Subject to legal provenance, CITES permits, and local wildlife trade compliance)
Rarity Assessment
Uncommon in private collections due to legal protections (CITES / Endangered Species Act restrictions)
Scientific Significance
High osteological utility for anatomical reference, comparative morphometrics, and educational instruction regarding marine reptile cranial morphology.
Preparation Recommendations
Keep in a temperature-controlled, UV-protected environment. Clean gently with dry soft brushes; avoid harsh chemical detergents or moisture exposure to prevent bone degradation.
Notable Features
Smooth, porous bone matrix with distinct cranial suture lines, exceptionally large orbit openings characteristic of pelagic marine turtles, and hooked anterior jaw structure.
