Fossils are defined as the remains of ancient organisms. Fossils are obtained from impressions left after an organism decays. There are different kinds of fossils depending on the material they are made of and how they were formed.

Alternatively, fossils could be plant resins or tar that preserved a specimen within.
The heart is a vital organ, and its functioning is essential to life.
All your other organs may fail, and you will still be alive. Even if your brain stops working, and your heart is healthy, you will be alive in the vegetative state where you won't be conscious at all. However, once your heart stops working, you die, which means it is the most important organ in your body.
