Spinosaurus vertebra

Polished Spinosaurus Vertebra

This specimen is a remarkable section of a vertebra from the Spinosaurus aegyptiacus, the largest known carnivorous dinosaur to ever walk the Earth. Unlike raw fossil fragments, this piece has been expertly cut and polished on one or more faces, revealing the intricate internal bone architecture that sustained this massive aquatic predator during the Cretaceous period.

Description & Visuals

The polished surface of this vertebra offers a "window" into prehistoric biology. The process of permineralization has replaced the original organic marrow with minerals, creating a dense, stone-like texture that takes a high, glass-like shine. Under light, the cancellous (spongy) bone structure is clearly visible, showcasing a complex web of mineralized cells. The unpolished sides maintain their original, rugged fossil texture, providing a beautiful contrast between the raw find and the laboratory-finished face.

Specimen Details

• Species: Spinosaurus aegyptiacus

• Age: Late Cretaceous (approx. 95–100 million years old)

• Origin: Kem Kem Group, Morocco

• Finish: Hand-polished face with a natural, fossilized exterior

• Coloration: Typically ranges from warm desert tans and sandy ochres to deep, iron-rich reddish-browns.

Key Features

• Internal Anatomy: The polished face allows for a rare look at the internal trabecular bone structure, which is often hidden in un-prepped specimens.

• Premium Aesthetic: The "shiny" polished finish makes this piece an ideal display specimen for a desk, shelf, or cabinet, catching the light and highlighting the mineral depth.

• Iconic Species: As one of the most famous and unique dinosaurs (known for its sail and semi-aquatic lifestyle), Spinosaurus material is a staple for any serious fossil collection.

• Tactile Experience: The contrast between the smooth, glass-like polished face and the gritty, ancient texture of the bone exterior makes it a very engaging piece to handle.

Important Notes

• Authenticity: This is a genuine dinosaur bone fossil. Due to the nature of the Kem Kem deposits, many vertebrae are found as partials or sections; this piece has been stabilized and polished to enhance its display value.

• Handling: While fossilized bone is essentially stone, it can be brittle. Avoid dropping on hard surfaces or exposing it to acidic cleaning agents.

• Cleaning: To maintain the shine on the polished face, a simple wipe with a dry microfiber cloth is all that is required.
