Evaporations that made the salt deposits in Syracuse New York and Detroit Michigan?
The salt deposits in Syracuse, New York, were formed from the evaporation of seawater during the Devonian Period around 400 million years ago. In Detroit, Michigan, the salt deposits were formed from the evaporation of seawater in the Michigan Basin during the Silurian Period around 400-425 million years ago. This process left behind layers of salt that eventually became the salt deposits found in these locations today.

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.
