表16 新种腓骨科尔尼菊石（Kornia fibula sp. nov.）的壳体个体发育
壳体直径8mm时：
壳体形态：厚球状；内卷
螺环横截面形态：强烈扁缩；极强烈包卷
螺环扩张参数：极低（螺环宽度（whorl width, ww）/壳体直径（conch diameter, dm）≈1.00；脐宽（umbilical width, uw）/壳体直径（dm）≈0.12）
（ww/螺环高度（whorl height, wh）≈2.05；内脐区比率（Internal Umbilical Zone Ratio, IZR）≈0.65）
（螺环扩张速率（Whorl Expansion Rate, WER）≈1.45）
壳体直径20mm时：
壳体形态：厚球状；内卷
螺环横截面形态：中等扁缩；极强烈包卷
螺环扩张参数：低（ww/dm≈0.90；uw/dm≈0.12）
（ww/wh≈1.90；IZR≈0.60）
（WER≈1.50）
