Fossils from the Silurian Period are between 443.7 and 416 million years old.
The Silurian period followed the Ordovician period.
The most recent fossil found in New York was the Eurypterus remipes, the sea scorpion, which lived during the Silurian Period.

Silurian Period
Fossils of sharks have been found dating back to the Silurian period, more than 200 million years before the first dinosaurs.
The Devonian was the geological time period that followed the Silurian.
Ammonite
The Silurian period was between 443.7 - 416 million years ago, which means that it lasted around 27.7 million years.
On land
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.
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 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.
