D. terrelli (Newberry, 1873 [originally Dinichthys]) D. ? belgicus (Newberry) 1873 D. denisoni (Kulczycki) 1957 D. marsaisi Lehmann, 1956 D. magnificus (Hussakof & Bryant) 1919 D. missouriensis (Branson) 1914 D. newberryi (Clarke) 1885 D. amblyodoratus Carr & Hlavin, 2010 D. raveri Carr & Hlavin, 2010
體型最大的種類D. terrelli,其體長估計可達8.79米(28.8英尺)而體重則可達4 t(4.4 short ton),為目前人類已知最大型的盾皮魚[3][4][5]。和其他盾皮魚一樣,鄧氏魚的頭部由厚甲殼包覆,這降低了牠們的運動速度和靈敏度。口中不具有牙齒,但是其甲殼具有銳利的邊緣,形成類似嘴喙的結構[4]。鄧氏魚和其他盾皮魚可能是最早行體內受精的脊椎動物,這項特徵在現存的鯊魚上也可見到[6]。
