Placogorgia species A. SBMNH 422970, Light microscopy arrays, 10× magnification. A Some of the more unusually shaped sclerites B–C Several highly ornamented and distinctive sclerites. Crutch form ~80 µm tall, thin spindles measure in the range of 150–191 µm in length, larger, thicker spindles are ~250 µm long, with unusual forms, such as B, the tall, spikey sclerite measuring some 300–350 µm tall and that appearing as a very large quadriradiate (C) measuring 280 µm across.
