A good index fossil is one of an organism that rapidly evolves and is widespread throughout a geologic time period or periods. This makes it useful in determining the age of the rock formation in which it is contained.
The fossil that is found in the one rock layer rather than through many layers because that means that the organism lived for only one period of time and not many.
I think it cause being a dective is rude and annoying and it is so rude that they fired me as being a stupid detetive
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.
Because they give us the best estimate of how old all the other fossils are in that sedimentary layer.

Renal panal
There are rarer fossils, as in fossils that belong to creatures that haven't been discovered yet or are very uncommon, but no "best" fossil.
Which of the following is most likely to become preserved as a fossil? a jellyfisha clam shella leafa worm

Yes, index fossils are special fossils that act as geological tools enabling comparison in time of a range of geological units and environment. Normally, they are selected using certain attributes such as the fossil should be widespread, abundant, fast evolving, and independent of their environment.
Rocks in general are not dated, but a fossil would be.

Fossil coupon codes can be found on many sites, specifically coupon code sites. However, the best place to find coupon codes would be the official website for Fossil.
using your best fossil
The best is skull fossil with craniodose not shieldon witch is weak and loser like.
Probably the best condition for fossil creation/preservation would be aqueous catastrophism(ie... flood), stratum deposited in rapid succession. Quick coverage of plant or life form would/do present terrific fossils.The answer of 'Quick freezing' is not so likely. I can't think of anywhere there would suddenly be 'flash freezing' upon our planet. Life forms would have a chance to move away from such conditions of cold and plants would die out. Although death within a cold temperature area would lend to good preservation of a life form."Quick Freezing"
A biologically healthy soil would be very likely to produce the best crop.
