A mass extinction event/ice age marked the end of the Ordivician Period. The climate, location of landmasses, and number and diversity of species had changed dramatically since the beginning of the period. When the changes that were occurring during the mass extinction event leveled out, a new period began.
What else can I help you with?
Why do large masses of the evaporite sedimentary rocks exist in silurian rocks in western ny but are not forming there today?
Coming out of the late Ordovician extinction due to large landmasses at the South Pole, the Silurian was a period of a warming environment, likely with large arid areas with high evaporation rates. Maybe look at Silurian paleogeography to get a better idea of what was going on to allow this.

Why was the Silurian period named the silirian?
The Devonian was the geological time period that followed the Silurian.
Was there any volcanoes in the Silurian Time Period?
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.

What life forms existed in the silurian time period?
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.
When did brontoscorpio live?
silurian period
Where was Ohio during the silurian period?
At that time, the area that is now Ohio was in the southern hemisphere near the equator.
When did plants first colonize land?
In the paleozoic, more specifically the Silurian period. Liverworts had evolved by 472 million years ago, putting the very earliest land plants closer to the end of the Ordovician than at the beginning of the Silurian.
