Igneous rocks and most metamorphic rocks, of an igneous origin.

Sedimentary rocks, such as sandstone and limestone, commonly contain fossils. These rocks form from layers of sediment that accumulate over time, trapping and preserving the remains of plants and animals. Fossils are less commonly found in igneous and metamorphic rocks.
It depends on what kind of fossils. You may find micro fossils in metmorphosed sediments such as Gunflint Chert from pre-Cambrian times.
Only sedimentary rocks may contain fossils
Igneous rocks do not typically contain fossils because they form from molten material. Sedimentary rocks are the most likely to contain fossils, as they are formed from the accumulation of sediment where organisms can become buried and preserved. Metamorphic rocks, which are formed under high heat and pressure, can sometimes contain fossils that have undergone significant changes.
Sedimentary rocks formed organically typically contain fossils of plants and animals. These fossils are remnants of the organisms that lived in the area where the sedimentary rock was formed.
Metamorphic rocks do not typically contain fossils, as the intense heat and pressure involved in their formation often destroy any remnants of organic matter. Igneous rocks are formed from molten material and do not contain fossils. Sedimentary rocks, which form from the accumulation and compression of sediments, are the type of rock that commonly contain fossils.
Sedimentary rocks, such as shale, sandstone, and limestone, are most likely to contain fossils. These rocks form from the accumulation of sediment and often preserve the remains of plants and animals. Fossils are less commonly found in igneous and metamorphic rocks, as these rocks form from molten material and intense pressure and heat, which usually destroy any existing fossils.
Fossils. Fossils are traces or remains of ancient organisms that are often found preserved in sedimentary rocks. These rocks are formed from the deposition and solidification of sediment over time, providing an ideal environment for the preservation of fossils.
