- 2005, Samantha Sara Brittany Hopkins, Evolutionary History and Paleoecology of Aplodontoid Rodents, page 74:
- State 1 is coded for those taxa with a substantial difference in the depth of the basins between the central fossettid and all others, such that a mid- or late wear specimen will have the central fossettid still present and clearly-defined, while the others will all be worn away.
- 2008, Eric J. Sargis, Marian Dagosto, Mammalian Evolutionary Morphology, page 149:
- The p1 is smaller than the canine and is little more than a peg-like structure, ovoid in occlusal view with a tiny fossettid in the middle.
- 2010, Richard H. Madden, Alfredo A. Carlini, Maria Guiomar Vucetich, The Paleontology of Gran Barranca, page 149:
- When compared with taxa from the Mustersan and Tinguirican, Patagonhippus canterensis n. gen. et n. sp. and P. Dukei n. gen. et n. sp. share the absence of a posterior fossettid, but have a more hypsodont dentition.
