Carboniferous
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.

Ammonite
The Silurian period was between 443.7 - 416 million years ago, which means that it lasted around 27.7 million years.
On land
Most Silurian land was part of Gondwana, a continent centered on the South Pole
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.
