''Muttaburrasaurus'' had very powerful jaws equipped with shearing [[teeth]]. Whereas in more derived [[ornithopod]] species, the replacement teeth alternated with the previous tooth generation to form a tooth battery, in ''Muttaburrasaurus'', they grew directly under them, and only a single erupted generation was present, thus precluding a chewing motion. An additional basal trait was the lack of a primary ridge on the teeth sides, which show eleven lower ridges. In 1981, Molnar speculated that these qualities indicated an [[omnivorous]] diet, implying that ''Muttaburrasaurus'' occasionally ate carrion. In 1995, he changed his opinion, suspecting that ''Muttaburrasaurus''{{'}}s dental system is evolutionarily convergent with the [[ceratopsia]]n system of shearing teeth. They would have been an adaptation for eating tough vegetation such as [[cycad]]s.<ref>{{cite conference |last=Molnar |first=R.E. |author-link=Ralph Molnar |year=1995 |editor1-last=Sun |editor1-first=A. |editor2-last=Wang |editor2-first=Y. |title=Possible convergence in the jaw mechanisms of ceratopians and ''Muttaburrasaurus'' |conference=Sixth Symposium on Mesozoic Terrestrial Ecosystems and Biota, short papers |location=Beijing |publisher=China Ocean Press |pages=115–117}}</ref>
