Eldredeops Trilobite in SHALE MATRIX Extinct form of marine life, a many-legged arthropod (critter with a hard shell, segmented body, and jointed legs) that roamed the sandy bottoms of seas and coral reefs, 400 million years ago (mid-Devonian period), which are now slate stone fossils. Comes with information card. Eldredgeops (formerly Phacops) rana is a form of Trilobite from the Ludlowville Formation of Erie County New York. Phacops rana and its related genus can be recognized by its large eyes (which remind some observers of a frog's eyes — the specific name rana is a reference to a common frog), its fairly large size (up to 6 inches long), and its habit of rolling up into a ball like a pill bug. In order to protect themselves from predators, Phacops rana would roll into a ball with its hard exoskeleton on the outside as protection. Many other trilobites possessed the same ability, but Phacops rana nearly perfected it. The slightest amount of sediment would trigger their senses, and Phacops rana would be hidden in a tiny shelter made of its own body. Although this safety feature often helped them to evade predators, occasionally it backfired and the trilobite would be buried under heavy sediment. Their fossils can still be found in balled-up positions 400 million years later.
