Echinoderms date back as far as the Cambrian Period, approximately 541 million years ago, making them among the oldest complex animal groups on Earth. This \u003cstrong\u003eauthentic Crinoid columnal fossil specimen\u003c\/strong\u003e presents real fossilized crinoid columnal segments - the stacked disc-shaped sections that formed the stalk anchoring the living animal to the ocean floor.\u003c\/p\u003e\n\n\u003ch2\u003e\u003cstrong\u003e541 Million Years of Ocean Life - Still Alive Today\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe crinoid stalk is composed of hundreds of individual calcite disc segments called columnals, each perforated by a central canal through which the water vascular system of the animal passed. In the fossil record, these columnals separate easily and are among the most abundant Paleozoic marine fossils - beautiful disc-shaped pieces that have been collected and admired for centuries. This real feather star sea lily fossil display presents a selection of those columnals from a 541-million-year lineage still represented by living species in the world's oceans today.\u003c\/p\u003e\n\n\u003ch2\u003e\u003cstrong\u003eThe Authentic Crinoid Columnal Segments for Collectors and Classrooms\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis is not a cast.
