No. The hard bones are more likely to form a fossil. The soft parts will degenerate over time. This is why most of the fossils from the Pre-Cambrian and Cambrian periods are mostly shells, not the actual animals that inhabited them.
No. The organism might have decomposed, been eaten by scavengers, or eaten by another organism.
It is false. It is normally hard parts such as bones and shells that are fossilized.
yes because after something dies there is always a fossil or skeleton and it is always buried
no not all of them
no
False.
Harder parts of organisms become fossils. For example vasculature in plants and bones of animals are best preserves in the fossils.
The earliest fossils represent plants.
Answer by Ibrahim El-OseryConfidence votes 33.1KYes, fossils are the traces and remains of organisms and plants that were buried and maintained under pressure
Fossils are the mineralised remains of organisms and contain no organic material.
Any internal organs. Only bones become fossils.
No. Fossils are chemicals like stone that have replaced organisms after they die.
1.9 Billion, more depending on the amount of pasta consumed.
No, only a small number of organisms became fossils. Most dead organisms simply rot away or are eaten.
Those surrounded by skeletal structures

Fossils exist of nearly all formerly living organisms, with some exceptions, from single celled bacteria to the largest dinosaur. Marine organisms comprise the bulk of fossils that are easily available today.
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.
Fossils are proof of organisms that lived long ago
The most common fossils found are from bones, teeth and claws. Soft tissue such as skin, muscle and internal organs rarely become fossils because they generally decay far to quickly for the normal processes of fossilization.
Really, anything can be fosslized. It really all depends on where it died. if it died in a lake and the lake dried and a layed of ground eroded over it than it would become fossleized by the nutrients found in that layer of ground. Like I said, depens on where it died, all that the location needs to be is a place where nutrient rich soil can preserve the bones. It just may seem like only certain organisms can be fosslized because they are all found those areas with preserving soil.
