Reptiles & Mammal-like Creatures
- The Permian Period was a time long before dinosaurs.
- Many different kinds of animals lived during the Permian.
- Some animals had backbones, and some did not.
- A backbone helps support an animal’s body.
- Animals with backbones are called vertebrates.
- Animals without backbones are called invertebrates.
- Scientists group animals by how their bodies are built.
Level 2
- The Permian Period lasted from about 299 to 252 million years ago.
- Scientists classify animals by shared physical traits.
- One major trait is the presence or absence of a backbone.
- Vertebrates have internal skeletons that support body weight and movement.
- Invertebrates lack backbones and rely on other structures for support.
- During the Permian, both vertebrates and invertebrates filled important ecological roles.
- Body structure influenced how animals moved, fed, and survived in Permian environments.

Permian Period
Earth is home to a wide variety of animals, including both vertebrates and invertebrates, living on land and in the seas.
Level 1
- What is the Permian Period?
A long time ago when many kinds of animals lived on Earth. - What is a backbone?
A structure inside the body that helps support it. - What is a vertebrate?
An animal with a backbone. - What is an invertebrate?
An animal without a backbone. - Why do scientists group animals by body traits?
To understand how animals are alike and different.
Level 2
- Why is having a backbone helpful for animals living on land?
It helps support body weight and allows stronger movement. - How did vertebrates and invertebrates differ during the Permian?
Vertebrates had internal skeletons, while invertebrates used other support systems. - Does not having a backbone mean an animal is less successful? Why or why not?
No. Invertebrates survived using different strategies suited to their environments. - Why is body structure important for classification?
Because it affects how animals move, grow, and survive. - How can studying Permian animals help scientists understand life today?
It shows how body plans evolved and persisted over time.
