RARE: Giant Turtle Shell Fossil – Large Section, Cretaceous, Australia

Description This listing offers a rare and substantial fossil section of a giant turtle shell, dating to the Cretaceous Period, and originating from Australia. This is a large carapace (shell) fragment, representing a prehistoric marine or freshwater turtle that lived during the age of the dinosaurs. Fossil Type: Specimen: Turtle Shell Fossil (Carapace Section) Likely from a large cryptodiran turtle based on structural and regional indicators Geological Context: Period: Cretaceous Estimated Age: ~100–66 million years ago (exact stage unspecified due to locality constraints) Depositional Environment: Likely fluvial or marginal marine settings; turtles during this time inhabited both freshwater rivers and coastal marine lagoons Preservation: Mineral replacement of original shell bone; stable and consolidated, with visible scute impressions or bone texture in many specimens Morphological Features: Broad, gently curved shell fragment from the carapace (top of the shell) Possible preserved sutures between scutes (the bony plates of the shell) Textured surface consistent with dermal ossifications of large Cretaceous turtles Dense, heavy fossilised bone with natural weathering and coloration Scientific Importance: Turtle fossils from the Cretaceous of Australia are rare and often fragmentary, making this large, intact section particularly desirable for collectors or research reference Contributes to the understanding of turtle diversity in Gondwanan continents during the Mesozoic era May be associated with genera such as Notochelone, Bouliachelys, or other large extinct marine cryptodires depending on region Locality Information: Australia – Specific site undisclosed, but Cretaceous turtle remains are known from deposits in Queensland and New South Wales, especially in areas formerly covered by inland seas and floodplains Authenticity & Display: All of our fossils are 100% Genuine Specimens and are supplied with a Certificate of Authenticity.
