The Silurian period spans from 443 to 419 million years ago. The earliest dinosaurs evolved 231 million years ago. That means there were no dinosaurs at all during the Silurian.

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.
