Description from the seller
An object embodying millions of years of history: this smooth sphere comes from a rare fossil deposit of madreporic coral from Madagascar, transformed into natural stone through a long, slow process, where time replaced organic matter with minerals.
The result is a fascinating interweaving of concentric, ovoid, and cavernous structures that tell the story of ancient colonial organisms that lived in seas now long gone.
The warm, earthy hue, with shades ranging from honey to golden brown, gives this sphere a strong decorative presence, making it perfect for both the collection and for environments inspired by nature and deep time.
Commercial name: Madagascar fossil coral
Geological age: Lower Cretaceous (about 140-100 million years ago)
Origin: Western Madagascar
Texture: Fossilization by silicification or secondary calcification
Ancient colonial corals lived in tropical marine environments, forming coral reefs. After their death, their calcareous skeletons were covered by marine sediments. Over time, diagenetic processes and mineralization gradually replaced the original structure with calcite, aragonite, or, in some cases, microcrystalline quartz. The result is a fossil rock with still recognizable skeletal structures.
