I WONDER - How Did Oviraptors Look After Their Eggs?

The Oviraptor was a swift dinosaur with long legs, capable of running fast. It had a toothless beak and likely consumed nuts, seeds, and vegetation. Oviraptors may have cooperated in pairs to incubate their eggs. They lived in arid, desert-like environments, adapting to dry conditions while brooding their eggs.

In what ways did Oviraptor's physical structure aid in its mobility?

What was the significance of Oviraptor's toothless beak?
