The Ordovician was in the Paleozoic era, and lasted from 505 to 438 million years ago. Trilobites were common then, and the earliest jawless, bony fish.

I have no idea what the oxygen levels were during the tertiary period!
The period during which life began to move on land was the Ordovician Period. It was during this time that evidence of plant spores from living fossils were found on land.
In this period, there was mostly water so you would have to be swimming a lot. But also there were mostly insects and water creatures at this time but no dinosaurs. So you wouldn't have to face dangers in Devonian time period
They are both time periods of the early Paleozoic. The Ordovician was approximately 490 million years ago, to 440 million years ago. The Silurian was approximately 440 million years ago, to 416 million years ago. The Silurian was the period immediately after the Ordovician. The two periods were divided by the second largest Mass extinction in history.
The Silurian went from 443.4 ± 1.5mya to 419.2 ± 3.2mya. It spanned from the conclusion of the Ordovician period to the beginning of the Devonian period. However the exact time frame of the Silurian period is unknown and could be off by millions of years because of the fact that that period was set during a significant extinction event. Therefore, the Silurian period lasted about 42 million years, give or take.
The middle of the Ordovician period would have been fairly mild. Plus there was abundant marine life for food. There was no animals, or plants on land. A traveler to this time Would need a shelter, and lots of fishing gear. Near the end of the period was an Ice Age, so winter clothing would be a must.
The Paleozoic Era spans six geologic time periods. The first was Cambrian and is the name given to a period of time in Earth's history, which spanned 570-510 million years ago. The Permian Period, which was the last period covers the time roughly 286 million years ago.
