Fossil species cannot be defined with the genetic definition. But then that's also true of most of the species that biologists define among living organisms.

To compare the relative ages of fossils scientists sometimes use an easily recognized species called?
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.
Why are there so few frog fossils?
The reason frog fossils are hard to come by is because of the softness of their bones.When the earth, soil and rocks move underground, their bones are easily destroyed. Which means fossils cannot form as easily.But saying that, one of the most famous fossils ever recovered is one of a frog, as you can see its facial features, which is rare for a fossil in general, let alone a frog fossil. More about that on the national Geographic website (click here).
If the same force is applied to push a pin and chopstick into a notice board which will be pushed more easily and why?
pin will be pushed in more easily because its surface area is less than chopstick
What is one reason why 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.
Why are fossils most likely to be found in sedimentary rock samples?
Most fossils are found in sedimentary rock, because igneous and metamorphic rock undergo great heat and pressure when forming, where as sedimentary rocks undergo much less pressure and heat to form, better preserving the fossil
Are index fossils easily recognizable?
Yes they are.

What fossils are most likely to be found in rocks?
Small shelled marine organisms are the most common easily observable fossils found in rocks.
Where can you easily find fossils in Britain?
Yes, look in a nursing home, get it, LOL
Do fossils break?
They aren't fragile but they are brittle. Fossils are mineral crystalisations of decayed organic matter. Basically they are rocks.
Did most fossils com from dinosaurs?
Fossils exist of nearly all formerly living organisms, with some exceptions, from single celled bacteria to the largest dinosaur. Marine organisms comprise the bulk of fossils that are easily available today.
Where does the public view fossils?
The public is able to view fossils most easily in most museums. This is the best way because there they are cleaned up and laid out with explanation of what the fossil is and where it was found.
What owl is an easily tamed species?

Why are birds poorly represented in the fossil record?
In order for birds to fly they need light and often hallow bones. Because of this they can easily be broken and do not easily form fossils.
How can scientists use the fossil record to provide evidence that evolution of organisms has occurred over time?
Using methods such as radioactive dating, scientists can determine the approximate age of a fossil or the rock in which it was found. Utilizing this knowledge of approximate age, scientists can compare progressive fossils, and identify changes. Changes are often minimal, and sometimes organisms do not change at all for large amounts of time, making comparative analysis of fossils a tedious task. Some eras produced better fossils than others. This can have several causes, such as particularly prolific habitation of environments that more easily produce fossils, general population booms, certain mass extinction events, and even happenstance. Because some eras produce better or more fossils, and some produce few to almost none, the fossil record can sometimes falter. In such cases, scientific investigations may be forced to fill in blanks between species using genetic analysis of preceding and proceeding species or groups within species, if the fossil(s) contain(s) any remaining genetic material. In other cases, computers will be used to recreate images of the species based on fossils, and identify progression between species. In any case, the fossil record is often used as a base off of which to obtain or recreate further information about an organism's evolutionary history.
