Dinnebitodon (meaning "Dinnebito (Wash) tooth"[1]), was a small quadrupedal animal, with a head 8 centimetres (3.1 in) in length,[1] belonging to the herbivorous Tritylodontidae family.

[1] There are five postcanine teeth in the upper jaw that would have been functional when Dinnebitodon was alive, with a sixth possibly erupting later in the animal's life.

Dinnebitodon was a terrestrial animal, living in the "Silty Facies"[1] of the Kayenta Formation, which would have represented an interdunal river deposit.

[2] The teeth resemble those of modern animals that feed on seeds and nuts,[3] suggesting that perhaps Dinnebitodon fed on similar foods present during the early Jurassic Period.

Considering it was living alongside its close relative Kayentatherium, some niche partitioning of the resources would have been necessary in order to avoid being outcompeted for a food source.
