GEOLOGY

Detailed explanation-1: -Other tracks show that dinosaurs did not drag their tails when they walked. Paleontologists can also estimate dinosaur gait and speed from some footprint track ways. If the footprints are close together, this might show they were running. If the footprints are spaced farther apart, the dinosaurs may have been walking.

Detailed explanation-2: -Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.

Detailed explanation-3: -Paleontological resources, or fossils, are any evidence of past life preserved in geologic context. They are a tangible connection to life, landscapes, and climates of the past. They show us how life, landscapes, and climate have changed over time and how living things responded to those changes.

Detailed explanation-4: -Explanation: Paleontologists are specialized types of scientists that study prehistoric life from fossilized evidence to infer what life was like long ago.

Detailed explanation-5: -What might a paleontologist conclude if she found a trilobite fossil in a desert? Trilobites lived in desert environments at one time. The desert was covered by water in the past.
