Heterodontosaurus lived in the Early Jurassic period, around 200-190 million years ago.
For example, Heterodontosaurus tucki.
Yes. You might be wondering if it really eats plants, why did it have huge fangs? The Heterodontosaurus had giant fangs to scare it's enemy away not to eat meat. Intimidation is always a great defense.

The large tusks of Heterodontosaurus, a small dinosaur from the Early Jurassic period, were likely used for a combination of purposes, including defense against predators and possibly for social interactions or display. These tusks may have also played a role in foraging, as they could have been used to strip foliage or access food sources. Their unique dental morphology suggests a specialized diet, and the tusks could have aided in processing plant material.
Good work this is a hard question to answer all because all dinosaurs can be harmful in there own way but if you would have to pick i would say heterodontosaurus may have to be my pick of least harmful, A. its a plant eater B. its smaller then us C. if they were alive today and you were able to spot one it would run away.

There are dinosaurs in all three categories. Dinosaurs were an incredibly diverse group of animals. However, there are far fewer varieties of dinosaur omnivores than either herbivores or carnivores. For example: Two Herbivorous Dinosaurs: Triceratops and Ankylosaurus Two Carnivorous Dinosaurs: Tyrannosaurus Rex and Allosaurus Two Omnivorous Dinosaurs: Ornithomimus and Heterodontosaurus

Yes most of them eat meat and some eat plantsMost dinosaurs were either strictly carnivorous or herbivorous, however the following groups are possible omnivores: primitive ornithischians (e.g. Heterodontosaurus tucki)pachycephalosaursthe sauropodomorph Panphagia protosoviraptorosaurstherizinosaurstroodontsThere's some debate about this one but I think it is an omivore its Coelophysis.We actually only know a few omnivorous dinosaurs. The only one I actually know is Oviraptor.NEW PERSON EDITING:Other then the Oviraptor, there is the Ornithomimus.Only a few of the known dinosaurs were omnivores (eating both plants and animals). Some examples of omnivores are Ornithomimus and Oviraptor, which ate plants, eggs, insects, etc. Also, most herbivores are "accidental omnivores" in that when they are eating plants, they also ingest a lot of insects and small animals.A dinosaur that eats meat and plants.Heterodontosaurids, some prosauropods, and ornithomimids are probably all omnivorous, but the best candidates for dinosaur omnivory are troodonts and oviraptors. If you had to name one dinosaur that you knew for sure was omnivorous, it would be the basal therizinosaur Falcarius.
A list of some known dinosaurs.Note that there are actually over 700 species of discovered dinosaurs. Only 540 of them currently have official names. The others are awaiting naming.There are also at least a further 900-1500 species that are currently undiscovered in the Earth's crusts or will never be discovered due to their fossils being destroyed completely by human activity or Earth's surface
