Teeth indicate that they would not eat grass, but scat says they did.

I've got plenty of stones that came out of dino stomachs that were used to grind food. Like birds, they had rocks do some of the digesetive work.

These stones look like they were tumbled round and polished. They are very easy to find in Utah.
