Excerpt from Bulletin of the Museum of Comparative Zooelogy at Harvard College, Vol. 50: Nos. 1-9; May, 1906-May, 1907 These monstrous creatures have been considered by Woodward and others as mailed Dipnoans, but their singular jaws are quite unlike those of the Dipneusti, and very remote from any structures in the ordinary fish. The turtle-like mandi bles seem to be formed of dermal elements, in which there lies little homology to the jaws of a fish and not much more with the jaws Of Dipnoan or shark.
