Dating from 542 million years ago, rocks of lineages that gave rise to modern organisms, as well as many lineages that have become extinct. During the early Palezoic, virtually all life was aquatic, but by about 400 million years ago, plants and animals were well established on land.

Footprints of animals left on sand dunes about 530 million years ago indicates that animals ventured onto land early in the Cambrian.
What else can I help you with?
When did the first land plants and animals appear in the fossil record?
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.
Which lived on land first plants or animals?
plants so the animals can have oxygen
When did the first animal appear on earth?
During the Silurian era the first simple animals began to appear on land. It is thought that this is due to the development of the Ozone layer protecting non-aquatic life for UV radiation. (This refers to the appearance of animals on dry land. Animals in the sea existed long before.) In the late pre-cambrian multi-cellular life appear in the sea due to the presence of high oxygen level in the atmosphere. Here is another: A small micro organism, having single cell born in sea, it had characteristics of both plant and animal. Hence it is the first plant as well as first animal. Some millions of year back. The first known fossils of what is possibly animal life appear in the Ediacara biota just prior to the Cambrian era. ca. 635-542 Ma see link

The first animals to live successfully on land were?
The first vertebrates to live on land did not come out of the sea until 370 billion years ago. Those first land vertebrates were amphibians. Several structural changes in the bodies of amphibians occurred as they adapted to life on land. Amphibians had moist breathing sacs -lungs- which allowed the animals to absorb oxygen from air. The limbs of amphibians are thought to have derived from the bones of fish fins. Because of there strong flexible internal skeletons the bodies of vertebrates can be much larger than those of insects. While amphibians were well adapted tp their environment, a new group had evolved from them. They evolved to reptiles but we are on the subject of the first land animal so that's that.

The first animals to enter land were the invertebrates, followed by some fish which later evolved into amphibians.
What animal is believed to be the first to appear on land?
Dinosaurs
Did animal appear first or did plant appear first?
Scientists believe that animals evolved from single-celled organisms in the oceans around 600 million years ago, making them the first to appear. Plants, on the other hand, evolved from ancient algae and appeared on land around 450 million years ago.
