* Name: Asteriacites lumbricalis * Trace Maker: Brittle star (Class Ophiuroidea) * Geological Age: Rhaetian Stage, Late Triassic * Timeframe: Approximately 208.5 to 201.3 million years ago * Findspot: La Voulte-sur-Rhône, Ardèche, France * Formation/Depositional Environment: Shallow marine sandstone; low-energy, well-oxygenated seabed * Morphology: Star-shaped imprint with five radiating, sinuous arms—resting trace of a brittle star * Paleoenvironmental Significance: Indicates calm, shallow marine conditions just before the Triassic–Jurassic extinction event This Asteriacites lumbricalis is an exceptional ichnofossil—an ancient resting trace left by a brittle star on a soft seabed over 200 million years ago, during the Rhaetian Stage of the Late Triassic. Discovered in the marine sandstones of La Voulte-sur-Rhône, France, it captures the elegant, star-like imprint of a prehistoric echinoderm just before the dawn of the Jurassic. Its five sinuous arms and finely preserved symmetry offer not only scientific insight but also natural aesthetic beauty. A rare and authentic piece of Earth's deep marine history—perfect for collectors seeking both scientific value and visual appeal. Matrix is 12 x 4,5 cm.
