Primitive sharks like Stelacanthus, predatory fish like Dunkleosteus, and primitive yet huge arthropods and amphibians,
During the devonian time period most of land was under water.
A common Devonian fossil is the trilobite, which was an ancient marine arthropod with a hard exoskeleton. Trilobites were diverse and abundant during the Devonian period, with many different species found in rocks from this time period. Their distinctive appearance and widespread distribution make them one of the most well-known fossils from the Devonian period.
The Devonian Period began approximately 419 million years ago, while the Pennsylvanian Period started around 323 million years ago. This results in a separation of about 96 million years between the beginning of the Devonian and the beginning of the Pennsylvanian.

Yes, trilobites were most abundant and diverse during the Devonian period, which was from about 419 to 359 million years ago. They were a group of marine arthropods that existed for over 270 million years before going extinct around the end of the Permian period.

If you mean animals as in insects (arthropods), they came in around the Devonian period of the Paleozoic era If you mean animals as in fish, amphibians etc then they came in at the same time as the arthropods
The Devonian Period
The plants of the Devonian period were very small. The animals that survived were cartilaginous fish like sharks and rays. Some squid and octopus survived as well.
The period after the Devonian Period (416 to 359.2Ma) is the Carboniferous Period (359.2 to 299Ma).
Being in the vicinity of a Dunkleosteus, a large armored fish that liked to eat.
Fish first appeared in the Cambrian period, long before the Devonian.
The Devonian period lasted from 416 million years ago to 359.2 million years ago.
During the devonian time period most of land was under water.

The Devonian Period
The Carboniferous period followed the Devonian period and was characterized by extensive coal forests and the emergence of early reptiles. The Devonian period is known for the diversification of fish and the development of forests on land.
