The image depicts two distinct seashells resting on a light brown wooden surface within the city of Leudelange, Luxembourg. The upper shell is an elongated, conical specimen, oriented horizontally, measuring approximately 8-10 cm in length. It presents a segmented brown body with regular, fine, light beige vertical striations. The wider left end appears damaged or truncated, while the right end tapers to a sharp point, revealing a small, light-colored protuberance at its tip. The lower shell, positioned below and slightly to the right of the upper shell, is a smaller, globular to conically-spiraled specimen, approximately 4-5 cm in length. Its surface is predominantly white with intricate, irregular yellowish-brown reticulated patterns. The apex, oriented towards the upper left, is sharp and light grey. Both shells rest on a light-colored wooden surface exhibiting visible grain patterns and minor surface imperfections. A distinct circular white residue, approximately 1 cm in diameter, is present on the wood near the lower shell's apex. Additional scattered white particulate residue is also visible on the wooden surface.
