Considering the fact that Protoceratops has a similar build to Pachyrhinosaurus, it could be given bone break, plus with the most famous Protoceratops and Velociraptor fossil in the world has a Protoceratops breaking the arm of a Velociraptor with its beak and not letting go for over 75 million years. Maybe Proto could be given a grab mechanic similar to Deinosuchus, that can inflict bone break, maybe?
