Manuel Quiring

This exquisite Nautilus Cenoceras fossil from Madagascar has been carefully sliced in half and beautifully polished to showcase the intricate internal structure.

The fossil offers a detailed view of the buoyancy system, with the siphuncle clearly visible as it connects the fully mineralized septa, a remarkable feature that demonstrates the creature’s unique adaptation for controlling buoyancy.

The specimen is not only stunning for its vibrant, natural colors but also for its translucent quality. 
The siphuncle is visible through the fossil, allowing you to admire the internal passageways and structures in stunning detail. 

The colors range from soft amber to deep golden hues, creating a mesmerizing effect that highlights the age and history embedded within the fossil.

While Nautilus fossils are fascinating in their own right, a specimen like this—showing the siphuncle and the translucent nature—is incredibly rare and truly exceptional. 

It combines beauty, scientific intrigue, and natural history in one breathtaking piece. 
Perfect for collectors and enthusiasts alike, this fossil is a rare gem that will stand out in any collection or space, bringing both artistic elegance and a deeper understanding of ancient life.

It will come with acrilic stands.

Boeny Region, Madagascar
