The Earth's surface was covered mostly with water. There was a very small part of land that was dry and above water.
During the devonian time period most of land was under water.

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 environment in the tertiary period was mostly covered with trees and grass.
Some dangerous animals in the Devonian period included jawless fish like Dunkleosteus, which had powerful jaws and sharp teeth for hunting. Other predators included early sharks and large eurypterids (sea scorpions), which were top predators in the ancient oceans.

there was no quarternary period, so make up a climate for your made up time period.
Warmer climate
Ammonite shells.A fossil that looks like a spiral or a rams horns is called an ammonite. Ammonites is extinct group of marine invertebrate animals that appeared during the Devonian period.
During the Tertiary Period, the surface of the earth looked much like it does today. It was quite warm with periods of cold much like today.
The surface bedrock of most of the Allegheny Plateau landscape region in New York state is predominantly from the Devonian period, which occurred approximately 419-359 million years ago. This bedrock consists mainly of sedimentary rocks like shale, sandstone, and limestone, which were deposited during this geologic time period.
