Cambrian Period
Actually the correct answer to this question is the "Pennsylvanian Period".
Fossils of animals and plants can be found in sedimentary rock (limestone, chalk, slate, etc).
Fossils can be any Kingdom. We have found fossils of plants, worms, animals plus many others.
Modern plants and animals resemble fossils found in the same area.
Harder parts of organisms become fossils. For example vasculature in plants and bones of animals are best preserves in the fossils.
Glucose is found in both plants and animals. Plants produce glucose by photosynthesis, and animals consume glucose (it is the first reactant for cellular respiration).
yea most plants and animals do leave behind fossils. scientists have found many of them from the pre-historic eras.
The fossils were first found in 1983
Fossils that have been preserved in ice or snow are known as frozen fossils. Generally, frozen fossils are associated with plants and animals that lived during the Ice Age.
fossils
The kind and numbers of fossils found in different kinds of rocks give clues about past ecosystems. Fossils give evidence that, in any ecosystem, some plants and animals survive well, and some do not.
I think the answer you're looking for is fossils. Fossils are remnants or imprints of living things, such as animals and plants, which are from past geologic age and found in the earth's crust.
Because very specific conditions need to occur for fossils to both form and also survive through to the present day. Most dead animals and plants are not fossilized and many that were must have been subjected to erosion and other destructive processes. Many fossils which have formed and survived just haven't been found.
