The most marine fossils are found in sedimentary rock
fish fossils and little animal fossils and also shells

molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.
Fossils have layer upon layer of hardened tissue. Therefore they are quite rough in texture where the insides are more malleable. Depending on what the fossil is of some fossils give off a sour aroma. Most of the time animal fossils deteriate at a faster rate than fossils of humans or shells. Fossils are a unique study and I you study them further.

When most people think of fossils they think of dinosaur skeletons and large bones, but there are many different types of fossils to be found. Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils. Body fossils show us what a plant or animal looked like. The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves. These can be mould and cast fossils, like most of the fossilised dinosaur skeletons and big bones we see, replacement fossils, like petrified wood, or whole body fossils - mammoths caught in ice, or insects trapped in amber. Petrified wood, frozen mammoths, and insects in amber are all body fossils. The second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!). Footprints and coprolite are trace fossils - they show us how an animal lived.
The most common four types of fossils are:mold fossils(a fossilized impression made in the substrate - a negative image of the organism)cast fossils(formed when a mold is filled in)trace fossils = ichnofossils(fossilized nests, gastroliths, burrows, footprints, etc.)true form fossils(fossils of the actual animal or animal part).
Animal parts that are soft and don't have a skeleton leave the worst imprints. Fossils are made with animal parts that are hard and durable.
DNA. fossils do not necessarily mean two animals are closley related
The first dunkin donuts was there and mamoth fossils were found
Fossils form when something dies and it decays over theyears. Thenall you see are the bones. Like dinosaurs bones!
