Probably, carbonateous fossil.
An index fossil is formed from the remains of an animal that evolved and lived for a precisely defined (and hopefully short) period of time, they are used to define and identify geologic periods. The best index fossils are wide spread (globally) and numerous (commonly found). They frequently (but not always) bottom dwelling or burrowing organisms with hard parts to their body structure because such organisms are most likely to regularly leave remains that can be fossilized.
No. The hard bones are more likely to form a fossil. The soft parts will degenerate over time. This is why most of the fossils from the Pre-Cambrian and Cambrian periods are mostly shells, not the actual animals that inhabited them.
yes, becasue it shows how old the fossil really is and the form and shape of it
A True form fossil is a fossil of the whole/entire body of the organism.
The earliest fossils known are in the form of stromatolites formed by cyanobacteria about 3.5 billion years ago. To say however that these are the first life forms is not likely to be correct. Cyanobacteria are already a relatively complex single celled organism. It is likely that simpler forms preceded them but so far no evidence of this has been found.
Fossilize The dinosaur was fossilized The snail shell will be fossilized if it is not disturbed.
If something got stuck in and enclosed by the liquid sap then it's fossilized.

Converted into a fossilized form so that the original appearance was preserved
Yes they can! In fact, shells are one of the easiest things to fossilize (the other is probably bone), and a majority of our knowledge on extinct, underwater invertebrates comes from their fossilized shells.

A fossil will most likely be found in a sedimentary rock because sedimentary rocks are made out of organic fragments such as rocks, shells, leaves, fossils, pebbles, and so on. A metamorphic rock would not hold a fossil because a metamorphic rock forms under great heat and pressure, and fossils would be destroyed under such conditions. An igneous rock would not hold a fossil because they form through the hardening of molten rock and fossils would be burned up and cremated in lava. Thus, fossils will most likely be found in a sedimentary rock.
Energy in fossilized plant and animal matter is stored in the form of chemical bonds within organic compounds. Over millions of years, heat and pressure transform these remains into fossil fuels, such as coal, oil, and natural gas. The energy originally captured from sunlight through photosynthesis in plants or consumed by animals is released when these fossil fuels are burned, converting the stored chemical energy into usable energy.

A rock that contains fossil seashells was most likely formed as a result of sedimentation.

this is stupid dont read this?
