Deinodon syntypes

As a side note, Cope (1866) designated three of the Deinodon horridus syntypes (ANSP 9533-9535) as the lectotype of Deinodon horridus. These teeth were also made the syntypes of Aublysodon mirandus by Leidy (1868) (which made Aublysodon mirandus a junior objective synonym of Deinodon horridus). Later, Marsh (1892) designated ANSP 9535 as the lectotype of Aublysodon mirandus and restricted the lectotype of Deinodon horridus to ANSP 9533 and ANSP 9534. Five syntypes of Deinodon horridus (ANSP 9530, 9536, 9541-9543) were designated as a new species of Dryptosaurus, D. kenabekides, by Hay (1899). Since ANSP 9535 is now the lectotype of Aublysodon mirandus following Marsh (1892) and ANSP 9530, 9536, 9541, 9542, and 9543 are now the syntypes of Dryptosaurus kenabekides, the name Deinodon horridus is currently restricted to the lectotype ANSP 9533 and ANSP 9534 following Cope (1866) and Marsh (1892).

There is no point to keep the referred species of Deinodon in the Deinodon species list, since Deinodon horridus is a nomen dubium following Russell (1970).
