What Are Nautilus Fossils?
Nautilus fossils are the fossilised remains of ancient marine molluscs, a part of the cephalopod family along with octopuses, squid, and extinct ammonites.
Nautilus fossils are famed for their stunning external coiled, spiral-patterned shells and colourful chambers.
How Old Are Nautilus Fossils?
Nautilus fossils available from Madagascan Direct date back to the Cretaceous Period at 120 million years old, in an era when the seas were full of Ammonite and Nautilus creatures that over time fossilised into the stunning specimens found today.
Nautilus: Living Fossils
Nautilus still exist in the present day, and they inhabit the deep coral reefs of the Indo-Pacific Ocean.
These live Nautilus creatures are termed "living fossils": a rare type of creature which is very similar in biology to its ancient fossil relatives.
Where Do Nautilus Fossils Come From?
Our Nautilus fossils were found in the jungles of Mahajanga on the North West coast of Madagascar, an island located near Africa which is famed for its fossil riches.
What Do Nautilus Fossils Look Like?
Nautilus Fossils display rich caramel and brown colours in intricate striped patterns.
These colours were caused by colourful calcite minerals replacing the original organic material present in the live Nautilus during the fossilisation process.
Nautilus specimens available at Madagascan Direct have been carefully hand-polished to the highest grade, enhancing the vivid colours of their shells.
The famous Chambered Nautilus (Nautilus Pompilius) has an external shell which protects the chambers within.
As the Nautilus creature grows, its chambers expand outwards in a stunning spiral shape.
The Nautilus body remains in the hard, outermost chamber so that it can be protected, and the other chambers are used to enable the Nautilus to float and sink.
Named after the Ancient Greek term for "sailor", Chambered Nautilus creatures are incredibly buoyant.
When the Nautilus is floating towards the surface of the ocean, the chambers are full of gas, helping the creature to float.
When the Nautilus needs to sink, a tube called the siphuncle that runs through the chambers opens, flooding the chambers with water so that the Nautilus becomes heavier and able to sink.
As carnivores, Nautilus creatures feed on fish and crustaceans: they swim towards prey using jet propulsion, meaning water inside their chambers is forcefully pushed out to propel them in their desired directions.
Sacred Geometry Of Nautilus Shells
In sacred geometry, the spiral shape has powerful spiritual significance, and signifies growth and expansion.
As Nautilus shells display distinctive logarithmic spiral shapes, Nautilus fossils embody this spiritual meaning of growth too.
A Nautilus shell is patterned in a very similar way to the sacred Golden Mean Spiral, a symbol of the infinite Fibonacci Sequence and the revered Golden Ratio.
As a result, Nautilus shells are believed to be strongly symbolic of order and perfection in not just the natural world, but the entire universe.
Ammonite shells are also thought to be sacred for this reason.
