I WONDER - What Did Omnivore Dinosaurs Eat?

The video discusses the dietary habits of a species that primarily consumed plants but also included a variety of other foods in their diet. They were not heavily reliant on hunting. Their diet included seeds, plants, insects, small mammals, other small dinosaurs, reptiles, and occasionally crustaceans from the sea.

What role do insects and small mammals play in the diet of these dinosaurs?

In addition to plants, what other types of food might these dinosaurs have consumed?
