1870 E. D. Cope in Trans. Amer. Philos. Soc. 14 130 As..the other pieces of the sternum have been found in England, it is certain that the genus is Cryptodire.

1948 Evolution 2 152/2 Pleurodire and cryptodire turtles date back to Cretaceous and Jurassic times respectively.

2000 Paleobiology 26 Suppl. 334/2 An analogous event happened with the origin of pleurodire and cryptodire turtles, where the origin of the shell set up the selective pressures and morphological opportunity for the development of neck retraction.

B. n.
