Index fossils are typically species that were widespread, abundant, and existed for a relatively short geological time period. Examples include trilobites, ammonites, and certain species of brachiopods or foraminifera. These organisms help geologists and paleontologists correlate the age of rock layers across different regions. Their distinctive features and rapid evolutionary changes make them reliable indicators of specific geological time frames.
Fossils are bones and remenants of organisms that lived a long time ago. I guess the bones of what were once organisms and bacteria that helped it to decay helps to form a fossil....
A mold or cast fossil is an example of a fossil that is not an organism. These fossils are formed when an organism's remains decay and leave behind an impression in sediment, creating a negative mold, or when minerals fill in the mold to create a positive cast.
If the certain fossils haven't been found yet that could result in a gap
It is conceivable that a fossil could be found among sedimentary rock crystals, and some dead organisms have actually been replaced by minerals which are composed of crystals. Fossils in gems and crystals from metamorphic or igneous processes--no.
Fossil types that provide paleontologists with well-preserved remains of organisms are typically those formed in conditions that allow for the retention of original organic material, such as amber or tar pits. These types of fossils can provide detailed information about the soft tissues or structures of ancient organisms, offering insights into their biology and behavior.

The fossils found in that area were of great importance. This is a sentence containing the word fossils.
Fossil species cannot be defined with the genetic definition. But then that's also true of most of the species that biologists define among living organisms.
Fossil records are incomplete because there are many random, destructive processes which can harm or destroy fossils. Think of all the violence of nature, earthquakes, floods, forest fires, landslides, volcanoes, etc. And fossils are not necessarily that durable. Many things can damage them. Some scavenger could chew on them. A large animal could step on them. It doesn't necessarily take an earthquake to damage a fossil. Fossils are just lying around, they are not protected or conserved, unless some paleontologist digs them up and puts them in a museum.

Yes, in Twist Mountain, a man will give you fossils for the Gen I -> IV fossil pokemon. It is possible he will give you a Skull Fossil.
Fossils could form in shale. Halite is table salt, a mineral with a crystalline structure that is not compatible with understood fossil formation methods.
I don't believe there is such thing as a living fossil, but you could find any fossil almost anywhere! Of course not in your kitchen, but any land of which you can dig into the earth of which the fossils decay.
The fossil of animals are evidence that support the theory of continental drift.
