mold fosssil
You could ask what era is it from.
Yes. You could bike or walk.
Arrowheads are not fossils, they were made by the Native Americans to use on the tips of their arrows.
an organism is a baby means a baby lives in another organism which is the mother.
Fossils could form in shale. Halite is table salt, a mineral with a crystalline structure that is not compatible with understood fossil formation methods.
It is called a mold fossil, which can become a cast fossil. After the soft parts of the animal rot away, a cavity remains (the mold fossil) which becomes filled with hardened sand or mud (the cast fossil).
A trace fossil can be anything from a coprolite (faeces) to a footprint. It is anything which proves the creature's existence without being the actual creature itself. For example, an ammonite shell is proof of its individual existence, but its faeces give us little information about its appearance. A fossil could be a cast, mold, or true form fossil.
A preserved fossil is an organism or Animal that has been PERFECTLY PRESERVED for lots of years, or however old it may be. For example, a wooly mammoth frozen in the ice for millions of years would be known as a preserved fossil.There are 2 different types of fossil preservation- preservation with alteration and without. With alteration also has different types. The type of organism you are looking for depends on the how it was preserved.
Something that is not preserved could be live, decomposed, etc.
You could ask what era is it from.
No, although a rock could contain the remains of some organisms. Coal, for instance.

an oxymoron, maybe a virus, something that died
As long as it could be preserved.
Any part of the body can be preserved as a fossil. The most common parts of the body to be fossilised are the hard parts such as claws, teeth and bones but it is also possible to fossilise soft tissue as well. One example of Thescelosaurus shows extensive soft tissue fossilisation. It was given the nick name of "Willo" the dinosaur with a heart.

Fossil have to be treated with such care because whenever a new generation come a long we could look back and see how this animal or organism has change over time. Ps : if you don't believe me then go and ask your mama
