Agate-Replaced Fossilized Clam, C. 34-56 Million Years Old, Eocene

Hold a tiny treasure from Earth’s distant past in the palm of your hand. These agate-replaced fossil clams are natural wonders — ancient bivalves from the Eocene epoch, transformed over 20 to 30 million years into shimmering, durable stone through the slow process of mineral replacement. Once living marine organisms, they are now exquisite fossils where agate has taken the place of the original shell material, preserving intricate natural detail in semi-translucent quartz.

Collected from the Dakhla region of Morocco, these fossils are most likely from the Laevastarte species, and measure between ¼" to ¾" in width—perfect for display, collecting, or simply marveling at the immense span of time they represent. While some may have minor chips, most are whole and intact.

Each fossilized clam is enclosed in a clear jar in a 5.6" acrylic display. Whether you're a seasoned fossil collector or a curious beginner, these agate-replaced clams are a beautiful, affordable glimpse into a prehistoric seafloor.
