       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.‭
