📖 1. Overview

Protoceratops andrewsi (genus Protoceratops) was a small herbivorous ceratopsian dinosaur that lived during the Late Cretaceous. It walked on four legs.

🦴 2. Anatomy & Morphology

The front of its mouth formed a beak, while the inside of its jaws held teeth for shearing and grinding food.

🔍 3. Fossil Record & Paleoecology

The Natural History Museum, London guide notes that it lived on plants. The figures given are representative values for the genus Protoceratops as a whole.
