Soft tissue.
The reason frog fossils are hard to come by is because of the softness of their bones.When the earth, soil and rocks move underground, their bones are easily destroyed. Which means fossils cannot form as easily.But saying that, one of the most famous fossils ever recovered is one of a frog, as you can see its facial features, which is rare for a fossil in general, let alone a frog fossil. More about that on the national Geographic website (click here).
mainly high pressure but you'll also need sediment such as rock or sand to smash it and as the soft parts of the plant decay they leave impressions on the rock
Mushrooms are very soft and have no cellulose or rigid fibers in them. They smash and disintegrate before they are fossilized.
Fossils can form from both soft parts and hard parts of organisms. Soft parts can become fossilized through processes like carbonization or preservation in amber, while hard parts like bones or shells can undergo mineralization or replacement to become fossils.
All dinosaur fossils of dinosaurs come from rocks. Most are bones, but some have been footprints, feces, skin impressions, or even mummified individuals, complete with fossilized soft tissue.
It is possible to find jellyfish fossils, but they are rare because jellyfish have soft bodies that are not easily preserved. In some cases, fossilized impressions of jellyfish have been discovered in certain types of sedimentary rocks that have preserved their soft tissue.
Chalk is a fossil itself and chalk is soft, and so while you might form a fossil; in it, it would not remain. Within chalk there is often harder rock - which sometimes does contain fossils.
Jellyfish fossils have been found in sedimentary rock formations around the world, generally in areas where ancient seas once existed. The soft-bodied nature of jellyfish makes their preservation as fossils rare, but in some cases, the impressions left by their bodies in sediment have been preserved and fossilized over millions of years. Scientists use careful excavation techniques to uncover and study these fossils to learn more about the evolution and history of jellyfish.
Their composition of soft materials.
Because for much of the earth's early history, living things were made up of soft tissue only.
Comparative form for "soft" is "more soft"!!
Because soft tissues, organs, skin and muscle doesn't turn into fossils.
because the fossilization process rarely preserves soft tissues and the fossils that do are very rare.
Because sedimentary rocks are soft rocks
Organisms that have hard parts such as bones, shells, or teeth are more likely to form fossils. Soft-bodied organisms can also be preserved in certain conditions, such as being quickly buried in sediment or trapped in amber.
