Almost all living organisms can leave fossils, but usually only the hard parts of plants and animals fossilize. Soft internal organs, muscle, and skin rapidly decay and are rarely preserved, but the bones and shells of animals are good candidates for fossilization.n this case, the fossil is a hole in the shape of the animal. By far the most common fossil remains are those of shelled invertebrate sea loving creatures such as snails, corrals, and clams. These make up most of the fossil record.
Which of the following pairs of organisms do you think would be placed most closely together? a) humans (homo sapiens) and chimpanzee (Pan troglodites) b) dog and a robin c) tuna fish and starfish d) whale and tuna fish e) Geospiza conirostris and Geospiza scandens. Which is the most accurate statement about evolutionâs fossil evidence? a) There is a complete record of fossils for the ancestors of most plants and animals. b) Paleontologists believe that most extinct forms of life formed fossils. c) We have complete fossil records for bones, shells, wood, as well as for soft-bodied organisms. d) There are few fairly complete fossil lineages, such as that for the ancestors of Equus.
