As with other ankylosaurians, "Minmi" was herbivorous Unlike most herbivorous dinosaurs, there is direct evidence of the diet of "Minmi": gut contents are known from the well-preserved nearly complete specimen. The gut contents consist of fragments of fibrous or vascular plant tissue, fruiting bodies, spherical seeds, and tissue (possibly from fern sporangia). The most common remains are the fibrous or vascular fragments, which have clean cut ends.
