Final answer:
The different types of fossils include Petrified, Mold, and Cast fossils, whereas 'Vaporized' is not a recognized type of fossilization. These fossils can be found in specific geological conditions and are valuable for understanding extinct species.
Step-by-step explanation:
Some different types of fossils include Petrified, Mold, and Cast fossils. Petrified fossils occur when minerals replace all or part of an organism's tissues, turning it into stone. Mold fossils are created when an organism leaves an impression in the substrate, and later, sediment fills in the impression, creating an external mold. A cast fossil, on the other hand, is formed when the space of an organism's body is filled in with minerals or sediments after the original material has dissolved, creating a replica of the organism's shape.
Vaporized is not an acknowledged form of fossilization. Fossils are often found in geological conditions such as within volcanic ash, limestone, and areas with mineralized groundwater. Graptolites, for instance, are commonly found preserved as two-dimensional carbonized impressions in certain types of rocks. The study of unaltered or permineralized bones and teeth can indicate the types of organisms that existed in the past and can be critical to biologists and paleontologists in understanding extinct species.
