This scientific illustration provides a detailed view of an ancient brittle-star discovered in the Lower Ludlow strata of the Upper Silurian. The first figure shows the organism from below, highlighting a circular central disc composed of numerous small, overlapping scales and five long, radiating arms. These arms are constructed of distinct, interlocking calcareous segments that gave the animal great flexibility. A second, highly magnified view focuses on a small portion of one arm, revealing the complex skeletal plates and the prominent lateral spines that once aided the creature in movement and sensory perception across the ancient seafloor. This genus represents an early group of ophiuroids, specialized echinoderms that thrived in Paleozoic marine environments.
