Yes, there were volcanoes present during the Silurian Period, but they were not as widespread or active as in some other periods. Volcanic activity during the Silurian likely contributed to changes in the Earth's climate and the composition of the atmosphere.
The Silurian period started off with a mass extinction of 60% of all marine life. During the Silurian bony fishes evolved setting the stage for the Devonian, which is referred to as the "Age of the Fish".
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.
