Animal life at Petrified Forest includes amphibians, birds, insects, spiders, mammals, and reptiles. Birds, lizards and rabbits are seen most frequently, though seasons and weather play a large role in determining what animals are active.
Mammals are warm-blooded vertebrates with hair, feed their young milk, and have a large, complex brain.
Reptiles are cold-blooded vertebrates. They have dry skin covered with scales or bony plates. They lay leathery eggs or give live birth.
Amphibians are cold-blooded vertebrates that don’t have scales. They live part of their lives in water and part on land.
