Docodon was a small animal that lived in North America during the late Jurassic. Though known mostly from teeth and jaw material, we can tell that Docodon had very complex teeth for the time, and that these may have been used to process a variety of things from insects to seeds and other things. This means that in the absence of actual stomach contents, Docodon is usually perceived to have been an omnivorous mammal.
