What type of fossil is preserved when the spaces are filled with minerals from groundwater?
A
index fossil
B
permineralized
C
mold
D
trace fossil
Explanation: 

Detailed explanation-1: -Petrified wood takes the process of permineralization one step further: minerals fill the pore spaces in the wood (the air that fills these pores is what makes modern wood float in water) and the original organic material (i.e., the wood) is replaced with minerals.

Detailed explanation-2: -A common form of fossilization is permineralization. This occurs when the pores of plant materials, bones, and shells are impregnated by mineral matter from the ground, lakes, or oceans. In some cases, the wood fibers and cellulose dissolve and are replaced minerals.

Detailed explanation-3: -Fossilized dinosaur bones, petrified wood, and many marine fossils were formed by permineralization.

Detailed explanation-4: -Permineralization, a type of fossilization, involves deposits of minerals within the cells of organisms. Water from the ground, lakes, or oceans seeps into the pores of organic tissue and forms a crystal cast with deposited minerals.

Detailed explanation-5: -Petrified fossils form when original materials that made up the organism are replaced with minerals.
