Definition: Crateromorphs are a group of extinct animals that lived during the Mesozoic era, characterized by their distinctive features and characteristics. These creatures were known for their large size, powerful jaws, and sharp teeth, which allowed them to thrive on tough, carnivorous plants. They had a wide range of adaptations for survival in their environments, including thick fur coats, specialized digestive systems for tough meat, and streamlined bodies that allowed them to move quickly through the sand and water they lived in.
