20mm nautiloid beautifully preserved in translucent chalcedony
Aturia angustata is an extinct nautiloid from the Cenozoic era, known for its beautifully coiled, disc-shaped shell and intricate suture patterns. Unlike modern nautiluses, Aturia had a more compressed shell, making it a sleek and agile swimmer in ancient seas. It lived during the Eocene to Miocene, and its fossils are rare and highly prized. With its elegant form and evolutionary significance, Aturia angustata is a stunning reminder of the rich diversity of shelled cephalopods that once thrived in Earth’s oceans.
