land animals
The first animal to live on land was probably an amphibian.
The first plants with spores, which indicates that they were land plants, appeared in the Middle Ordovician period, about 470 million years ago. First records of tetrapods, or land animals, show up in the fossil record around 370 million years ago.
Animals that live on land are referred to as terrestrial.
The first animals to enter land were the invertebrates, followed by some fish which later evolved into amphibians.
