GEOLOGY

Detailed explanation-1: -Preserved remains are types of fossils where the entirety of an animal, plant, or insect is preserved. These types of fossils can only be created under special circumstances that prevent the decomposition of the creature. Creatures preserved this way have been found in amber, tar, peat, and ice.

Detailed explanation-2: -In recent years, paleontologists have found insects, a snake, and even some remains of feathered dinosaurs entombed within the amber. No scientist has done more to catalog these amber fossils than Xing, whose research is partially funded by the National Geographic Society.

Detailed explanation-3: -Most fossils are hardened animal remains such as shells, bones, and teeth. Minerals replace the remains, forming a fossil of the hard skeletal body parts. Other fossils are impressions or other evidence of an organism preserved in rock.

Detailed explanation-4: -Fossils are everywhere you have sedimentary rock* deserts are actually rather poor at forming fossils compared to many other environments. They are FOUND more often in deserts because there are no plants or soil covering them up and no plant roots to rip them apart for minerals.
