Fire Red Iridescent Cleoniceras Ammonites from Madagascar
These beautiful fire red iridescent ammonites are some of my personal favourites when it comes to fossils. They offer a glimpse into the ancient oceans that once covered the landscapes of Madagascar.
Cleoniceras ammonites are ancient marine mollusks that once roamed the oceans during the Cretaceous period, around 120 million years ago. Fossilized remnants of these creatures serve as valuable time capsules, allowing us to unlock the mysteries of Earth's history. The Cleoniceras genus is known for its distinctive spiral shape and intricate chambers, providing valuable insights into the evolution of marine life.
Madagascar, the fourth largest island in the world, has long been a hotspot for paleontological discoveries. The island's unique geological history has preserved a rich tapestry of ancient life, making it a treasure trove for fossil enthusiasts and researchers alike.
The story of Cleoniceras ammonites in Madagascar unfolds against the backdrop of the island's diverse landscapes. Millions of years ago, Madagascar was submerged beneath the waves, forming a seabed that was home to a myriad of marine life, including the iconic Cleoniceras ammonite. Over time, geological processes uplifted the island, leaving behind a legacy of fossilized wonders.
The country's varied terrain and fossil-rich sites, such as the Mahajanga Province, offer a glimpse into the ancient oceans that once covered the island.
What sets the Cleoniceras ammonites from Madagascar apart is their breathtaking iridescence, particularly when exposed to light. The fossilized shells, composed primarily of aragonite and calcite, interact with light in a way that produces a stunning play of colours. The fire red hues, in particular, give these fossils an almost otherworldly appearance.
This iridescence is a result of the interaction between the fossilized shell material and the minerals present in the surrounding rock layers. The unique conditions under which these fossils formed contribute to the preservation of their vibrant colours, turning each Cleoniceras ammonite into a miniature work of art.
I will be listing these beautiful fire red ammonites over the coming months. Each one is unique. Some have greens, purples and reds when turned to the light.
