Fossils are the preserved remains or traces of organisms that lived in the geologic past. Trace fossils are made by marks left by organisms while still alive, such as tracks, burrows, and dung.Decomposition, weathering, and scavenging all contribute to what makes fossils so rare.Almost all fossils are found in sedimentary rock; almost none are found in metamorphic or igneous rock.Fossils are our only direct key to the past, informing us about migratory patterns, weather and environmental conditions, species' interaction, and animal behavior.Scientists use index fossils to place events on the geologic time scale. The organisms that become index fossils are chosen because they had relatively short geologic life spans, wide geographic ranges, and are easily identified.
The study of plants and animal remains is known as paleobotany and paleozoology. These fields involve examining fossilized plant and animal remains to understand their anatomy, ecology, evolution, and their interactions with the environment. It provides insights into the history of life on Earth and helps reconstruct ancient ecosystems.
Yes.
It is the nucleus, at the same time the nucleus is also easy to identify in the animal cell
An index fossil is formed from the remains of an animal that evolved and lived for a precisely defined (and hopefully short) period of time, they are used to define and identify geologic periods. The best index fossils are wide spread (globally) and numerous (commonly found). They frequently (but not always) bottom dwelling or burrowing organisms with hard parts to their body structure because such organisms are most likely to regularly leave remains that can be fossilized.
You have your grammar wrong.. :) That is " What is the effect of great geologic changes on plant and animal life" Welcome :)
FOSSILS ! comes from latin word Fossus which means "having been dug up". Anything that was once a living organism from a past geologic time is considered a fossil.
Please identify the animal print
The remains of an animal. -------------------------- Fossils are the remains of a dead plant or animal that have been preserved for a long time.
Detritivores feed on dead plant and animal remains.

There are so many that it's hard to name just a few (there are 6 geologic time periods that existed before the Triassic after all). A few are dimetrodon, arthropleura, the trilobite, meganeura, gorgonops, and ctenorhachis.
No. At one time yes. It must be very old. Definition of fossil per www.dictionary.com: any remains, impression, or trace of a living thing of a former geologic age, as a skeleton, footprint, etc.

When it is like that, the remains decompose and form into dirt.
No they are not.
