rapid burial and possession of hard parts.
There is currently no confirmed evidence of fossils on Mars. Sedimentary rocks are usually associated with the formation and preservation of fossils on Earth, so if fossils were to be found on Mars, they would likely be in sedimentary rocks.
Limestone, shale, sandstone, and chert are the biggies when it comes to fossils.
No, fossils are typically not found in metamorphic rocks. Metamorphic rocks form from the alteration of existing rocks due to heat and pressure, which can destroy any fossils present. Fossils are more commonly found in sedimentary rocks where the conditions for preservation are more favorable.
Fossils created when minerals gradually replace the organic material of an organism, preserving its shape and structure, are called petrified fossils or replacement fossils. Over time, the original material is dissolved, and minerals fill the space, creating a fossilized replica of the organism.
Fossils can form anywhere that conditions are conducive to preservation, such as in sedimentary rocks, tar pits, or ice. However, the likelihood of fossil formation varies depending on the environment and the organisms present.

i'm not sure but i think it's original preservation.
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.

No, shale is a finer-grained rock and will give better preservation than a sandstone.

Fossils are most commonly found in sedimentary rocks. These rocks form from the accumulation and cementation of sediment, which helps preserve the remains of organisms over time. Sedimentary rocks often provide the ideal conditions for the formation and preservation of fossils.

Cast fossils: Formed when minerals fill a mold left by a decayed organism. Mold fossils: Created when an organism's remains leave an impression in sediment that hardens into rock. Petrified fossils: Organic material replaced by minerals over time, forming a rock-like replica. Trace fossils: Evidence of an organism's activity (e.g., footprints or burrows) preserved in sedimentary rock. Carbon fossils: Organisms preserved in carbon-rich environments, like coal or oil deposits. Preserved fossils: Organisms remain intact or partially intact due to exceptional preservation conditions.
