To compare the relative ages of fossils, scientists use an early recognized species called an index fossil. An index fossil must have existed for a short period time and must have covered a wide geographical range.
Are fossil dead or alive?
No. At one time yes. It must be very old. Definition of fossil per www.dictionary.com: any remains, impression, or trace of a living thing of a former geologic age, as a skeleton, footprint, etc.
How do geologists figure out rock-layer puzzles?
Geologist must use their knowledge of the events that disturb or remove rock-layer sequences to help piece together the history of Earth as told by the rock record.

What information must first be obtained before the scientists can place the fossils in the ancestral time line of the dog?
"The age of the fossils
What is the importance of index fossils?
Index fossils are the fossils of short-lived species which, because of their short lives, can be used by scientists to identify the age of the rock strata in which they're found. (For example, if you know a certain species only lived in the Cambrian period, and you find some fossils of this species in some rock, then you know the other fossils you find in that rock must also have come from the Cambrian period.) Some examples of species that left behind index fossils, and their related historical periods, are:Billingsella corrugagta - Cambrian period, Palaeozoic eraCactocrinus multibrachiatus - Mississippian period, Palaeozoic eraScaphites hippocrepia - Cretaceous period, Mesozoic eraNeptunea tabulata - Quarternary period, Cenozoic eraSee the links below for more examples and info.
