organisms tend to decay before becoming a fossil
For the same reason you haven't got all your shoes since you were two years old: it's hard to find stuff, and it's hard to keep stuff.
The answer is the fossil record :D
-The tendency of loss at extinction boundaries to appear, because of incomplete sampling, more gradual in the fossil record than it actually was during the extinction event.

The fossil record provides nothing good for paleontologists.
when did the equus frist appear in the fossil record
The fossil record is incomplete.
The fossil record is incomplete.
The fossil record is incomplete because not all fossils have been discovered. In actuality it is unlikely that all fossils will ever be discovered given the hit and miss nature of fossil discovery which usually occurs through educated guess work. The fossil record will likely never be complete.
Because its all a lie. God created us all.
Fossil records are not complete. By some estimates, less than 1% of organisms that have lived appear in the fossil record.
The fossil record is basically the totality of fossils, discovered or undiscovered, and their placement within rock formations and sedimentary layers. The fossil record is important in helping us produce a chronology for the history of life on Earth as well as the evolutionary relationships between the organisms represented by the fossils. The number of fossils we have discovered remains incomplete, which is why we are continuously searching for more.
The answer is the fossil record :D
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.

The first animal life on Earth was in the ocean in the Precambrian time. The exact nature of the first animals is not known as the fossil record from that time is incomplete.
