370 milioni di anni fa Orthoceras Fossil Jurassic Jewelry Collection - Height: 79 mm - Width: 20 mm- 20 g - (1)

Orthoceras fossils are remnants of an extinct genus of cephalopods that lived approximately 370 million years ago, primarily during the Paleozoic era. They are characterized by their elongated, conical shells divided into chambers by septa connected by a siphuncle—a tubular structure that helped regulate buoyancy. These marine creatures are ancestral to modern squids and octopuses and are prized among collectors and enthusiasts for their distinctive and often beautifully preserved forms. Fossilized orthoceras are commonly found embedded in sedimentary rocks and are sometimes used in jewelry, where their natural patterns and ancient origin create unique, intriguing pieces. The specimen referenced is notable for its size and fine preservation, making it a compelling addition to any fossil or jewelry collection. Its Jurassic lineage adds scientific and aesthetic value, illustrating life from hundreds of millions of years ago.
