Protolith is a term used to describe the parent rock of a metamorphic rock. Conglomerate is a sedimentary rock that can be composed of clasts of sedimentary, igneous, or metamorphic rocks, or any number of combinations of all.
Igneous Rock
No, the oldest rocks on Earth are estimated to be about 4 billion years old and do not contain fossils. Fossils are typically found in sedimentary rocks that formed later, where the remains of plants and animals were preserved.
Undistributed rock layers may indicate that the layers have not been disturbed or deformed from their original horizontal positions. The oldest rock layers are typically found at the bottom of a sequence, while the youngest rock layers are found at the top, following the principle of superposition in geology.
You would most likely find the oldest seafloor in the deepest parts of the ocean, specifically in the abyssal plains. The seafloor in these regions is oldest because it is farthest away from the mid-ocean ridges where new seafloor is constantly being created through seafloor spreading.
YellowKnife Trench
Somewhere at the bottom of the Marianas Trench you would find the oldest rock of the oceanic crust. Somewhere else, however, there are older rocks on the ocean floor--those deposited by icebergs that have broken off of glaciers. Those erratic rocks could be much older than the oldest oceanic crust.

You would know because the youngest rock layer is always on the top, and the oldest is always at the bottom of the canyon.
The oldest rock layer in a canyon is typically the layer found at the bottom. This is because new layers of rock are deposited on top of older layers over time, resulting in a sequence with the oldest rocks located at the base of the canyon. Geologists use principles of stratigraphy, such as the Law of Superposition, to determine the relative ages of rock layers in a canyon.
