trilobites

During the Devonian period, animals that could live on land while still spending part of their lives in the water were called amphibians. In order to confirm this answer, we can break down the options provided and eliminate incorrect answers.

a) Trilobites: Trilobites were a type of marine arthropod that existed from the Cambrian to the Permian period. They did not have the ability to live on land.

b) Reptiles: Reptiles did not appear until later, during the Carboniferous period. Therefore, they were not the animals that evolved to live on land during the Devonian period.

c) Amphibians: Amphibians are the correct answer. These animals, such as early tetrapods and labyrinthodonts, were the first vertebrates to successfully transition from water to land. They still needed water for reproduction and spent part of their lives in aquatic environments.

d) Dinosaurs: Dinosaurs did not appear until the Triassic period, which was much later than the Devonian period. They were not the animals that evolved to live on land during this specific time period.

Therefore, the correct answer is c) amphibians.
