マトリックス上のオルソケラス化石—ディスプレイ用スタンド付きの装飾セット（スタンド同梱） - 動物化石 (No reserve price)

Elegant set of three natural fossil specimens featuring beautifully preserved Orthoceras embedded in stone matrix, presented on a modern black metal display stand (included). Each piece is individually mounted, creating a balanced and refined композиtion with strong visual impact.

The fossils display elongated, conical shells with characteristic internal chamber structures, clearly visible in section. The contrast between the dark fossilized Orthoceras and the lighter matrix enhances their natural patterns and gives the specimens a striking decorative appeal.

Orthoceras are extinct marine cephalopods that lived approximately 400 million years ago, during the Paleozoic era. Their distinctive straight shells make them highly recognizable and appreciated among collectors.

The three specimens vary in tone and composition:
- Two pieces in grey/black matrix with strong contrast and clearly defined fossil structures
- One specimen in a warmer, brownish matrix with multiple visible Orthoceras sections

The included display stand offers a clean, museum-style presentation, perfect for showcasing in a home, office, or private collection.
