evolution for the first blank
The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.
99% of all organism who lived once are now extinct, so a list would be more than extensive! Dinosaurs are the big fossils. Mammal fossils are big too. Human and proto-human fossils may be the biggest things in fossils ever.
Scientists learn about plants that are extinct by studying their fossils. These fossils will often preserve a plant's remains very well.
the answer is elemetary
Evidence of an organism's activities is recorded in trace fossils. These include tracks, fossilized dung, and burrow casts.
One observation that Darwin made was the fossilized armadillos and these fossils closely resemble, but were not identical to, the armadillos living in the area. Another observation he made was the fact that the plants and animals of the Galápagos Islands resembled those of the nearby coast of South America.
Because the only evidence of it is fossils that are thousands of years old, and it has never been seen in historical times.

Reptiles aren't extinct. Snakes are reptiles! Do you think they are just "fossils"?
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.

Yes, footprints that are preserved in rock, such as those of extinct dinosaurs, are fossils. Such fossils are known as ''trace fossils'' , as opposed to ''body fossils'' which are fossilized remnants of the hard parts of these ancient organisms.
