[3] The genus was first named with the description of the type species U. kroehleri by Hans-Dieter Sues in the journal Nature in 1991.

[2] U. kroehleri is known from several teeth found from the early middle Carnian Turkey Branch Formation of the Newark Supergroup in Virginia, uncovered from the Tomahawk locality.

[3] A single tooth from the Petrified Forest Formation of the Late Triassic Chinle Group, found at the Placerias Quarry at St. Johns, Arizona, has been identified as one of Uatchitodon.

MNA V3680 is the earliest example of a tetrapod with completely enclosed tooth canals for the delivery of oral toxins, which are seen today in elapid snakes.

MNA V3680, along with several other teeth from the Cumnock Formation near Raleigh, North Carolina, represent a second species of Uatchitodon, U. schneideri.

[3][9] U. schneideri was named in honor of Vince Schneider of the North Carolina Museum of Natural Sciences.

[10] The grooves of U. kroehleri may indicate that it had a lifestyle similar to the living gila monster, chewing prey to pass venom into it.
