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).
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.
