Metamorphic rocks are almost always from folded strata.

Are fossils frequently found in metamorphic rock?

There is a gradation between sedimentary or igneous rocks into metamorphic rocks. The higher the pressure and temperature, the more metamorphic it is. Some metamorphic rocks are so altered that they look much like an igneous rock. Others have only a little alteration.

If it is not highly altered there can be fossils. Slate is a metamorphic rock which was originally shale, and fossils are found in slate. Most fossils are found in sedimentary rocks because the rock is less altered.

Sedimentary rocks can be folded with relatively little alteration and fossils are frequently found in folded sedimentary rocks.
