Its Fossil Friday!
🌈🐚 A ~110-million-year-old masterpiece of nature.
This iridescent ammonite once swam in ancient seas during the Cretaceous Period. Buried for millions of years in what is now Madagascar, silica-rich waters transformed it into an opalized fossil, preserving its shell with a dazzling rainbow glow. The shimmering colors come from preserved nacre (mother of pearl) and microscopic silica structures that bend light into a natural kaleidoscope. ✨
Proof that science and art have been collaborating for millions of years. 🌍💎
