Silurian period
please write back saying how far you are away from silurian puzzle box and i will answer your question
The Ordovician period came first. It started 485.4 million years ago and finished 443.8 million years ago. Then came the Silurian and Devonian periods, followed at 358.9 million years ago by the Carboniferous.
Its the largest bug, kinda like a sea scorpion and is known to be taller than man! -- The eurypterids match the above description. Also, they first appeared in the Silurian period along with corals and early land plants.
The Silurian period.
Fossils from the Silurian Period are between 443.7 and 416 million years old.

Silurian Period
The Devonian was the geological time period that followed the Silurian.
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
During the Silurian period, most of the land was clustered around the equator in a supercontinent called Gondwana. It was mostly covered by shallow seas, with a warmer climate and diverse marine life. Compared to present-day continents, the landmasses were different in shape and position due to plate tectonics shifting over millions of years.
