Herbivore dinosaurs
914 genera whose own record in the Paleobiology Database carries the herbivore ecospace value.
Diet is the ecospace value recorded on each genus record. A genus whose record lists more than one ecospace diet appears under each diet it records, so these three diet pages together list more genera than the site holds.
