Salt water.
They may have possibly lived in fresh water. However, no fresh water fossils of trilobites have ever been recorded nor found. They were oceanic creatures :)
About 3% of the water on Earth is fresh. Only about .1% of the fresh water is visible on land. About 75% of the fresh water is locked in glaciers and ice caps. Then about 24.9% of the fresh water is underground.
Trilobites lived mainly in shallow seas near to the continents, although the continents we see today are not the same as they were when trilobites lived. Parts of the shallow seas in which they lived are now above sea level which is why we now find their fossils on dry land. Some areas now have trilobite fossils next to different rocks which contain totally different fossil trilobites showing that, at one time, there would have been an ocean separating them. Areas where you would find the fossils include USA, Canada, Norway, UK, Europe, Morocco, Myanmar (Burma), Russia and many other countries.
The water cycle renews the supply of fresh water on land.
Water. There is overall 70% water and only 30% land. However, 97% of water is saltwater, and the other 3% is fresh. Since 2% of that fresh water is frozen in the arctic, we humans can only use 1% for drinking.
Tsunami, water damage
I think water
Trilobites are extinct but they were marine animals.
Only about 3% of Earth's water is fresh. Two percent of the Earth's water (about 66% of all fresh water) is in solid form, found in ice caps and glaciers. Because it is frozen and so far away, the fresh water in ice caps is not available for use by people or plants. That leaves about 1% of all the Earth's water in a form usable to humans and land animals. This fresh water is found in lakes, rivers, streams, ponds, and in the ground. (A small amount of water is found as vapor in the atmosphere.)

a fresh water pond
A body of fresh water surrounded by land is a lake or pond.

fresh water, and salt water
a gulf!
The main sources of fresh water on land are snow and rain which fall as precipitation.
On land fresh, on sailboats salt water.
