What are the conditions needed for an index fossil to form?
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.
Do all organisms become fossils?
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.
Would research be amazed to find a 400 million years old fossil of a fish?
yes, becasue it shows how old the fossil really is and the form and shape of it
Fossilized evidence of Earth's first forms of life would consist of?
The earliest fossils known are in the form of stromatolites formed by cyanobacteria about 3.5 billion years ago. To say however that these are the first life forms is not likely to be correct. Cyanobacteria are already a relatively complex single celled organism. It is likely that simpler forms preceded them but so far no evidence of this has been found.
What is a true fossil?
A True form fossil is a fossil of the whole/entire body of the organism.
What is the verb form of fossil?
Fossilize The dinosaur was fossilized The snail shell will be fossilized if it is not disturbed.
How does a fossil of an animal form in amber?
If something got stuck in and enclosed by the liquid sap then it's fossilized.
How does a body fossil of a animal form a amber?
If something got stuck in and enclosed by the liquid sap then it's fossilized.
Which is more likely to form a fossil turtle or a tarantula?
A turtle is more likely to form a fossil than a tarantula due to its hard shell, which provides better protection and preservation during the fossilization process. Turtles have a bony structure that withstands decay, while tarantulas, being soft-bodied with exoskeletons, are less likely to be preserved in the fossil record. Additionally, turtles have existed for millions of years, increasing the chances of finding fossilized remains compared to tarantulas.
Which is more likely to form a fossil a turtle or tarantula explain?
A turtle is more likely to form a fossil than a tarantula due to its hard, bony shell, which provides better preservation potential. Fossils typically form from organisms with hard parts, as they are less prone to decay and more easily buried in sediment. In contrast, tarantulas have soft bodies that decompose quickly and are less likely to be fossilized. Therefore, the likelihood of fossilization is significantly higher for turtles.
Can form a fossil?
Yes they can! In fact, shells are one of the easiest things to fossilize (the other is probably bone), and a majority of our knowledge on extinct, underwater invertebrates comes from their fossilized shells.

What type of rock is most likely to hold a fossil?
A fossil will most likely be found in a sedimentary rock because sedimentary rocks are made out of organic fragments such as rocks, shells, leaves, fossils, pebbles, and so on. A metamorphic rock would not hold a fossil because a metamorphic rock forms under great heat and pressure, and fossils would be destroyed under such conditions. An igneous rock would not hold a fossil because they form through the hardening of molten rock and fossils would be burned up and cremated in lava. Thus, fossils will most likely be found in a sedimentary rock.
How is energy stored in fossilized plant and animal matter?
Energy in fossilized plant and animal matter is stored in the form of chemical bonds within organic compounds. Over millions of years, heat and pressure transform these remains into fossil fuels, such as coal, oil, and natural gas. The energy originally captured from sunlight through photosynthesis in plants or consumed by animals is released when these fossil fuels are burned, converting the stored chemical energy into usable energy.
