Period: Silurian Julia Wilson and Dillon Vroman

It was the third period in the Paleozoic era, and followed the Ordovician era along with the Devonian era

The plants that lived in the water had to adapt to the land or die

Some plants began to take root on land around 430 million years ago

The climate was very warm during this period which caused glaciers to melt and sea levels to rise

Silurian fossils show extensive reef building

Landmasses were low and sea levels were rising

The Silurian period occurred from 443 to 416 million years ago

The species that survived the mass extinction at the end of the Ordovician period branched out and developed new variations.

Fish with jaws were discovered.

The name Silurian came from a Scottish geologist, in 1835 he named a sequence of rocks in Whales and its borderland with England in honor to native people called Silures.
