What else can I help you with?
What are some aspects of an organism that cannot be studied using fossil evidence. Why don't fossils provide information about these characteristics?
Fossils can't usually provide information about the soft tissues of an organism because soft tissues rarely become fossilized. Also, fossils rarely provide information about interactions among organisms and thus tell us little about animal behavior.
What type of rock layer are tertiary fossils usually found in?
Tertiary fossils are usually found in sedimentary rock layers. Sedimentary rocks are formed by the accumulation and compression of sediments over time, making them a common host for preserving fossils from the Tertiary period.
Fossils usually provide paleontologists with information about each of the following except an organism?
Fossils usually provide paleontologists with information about an organism's age, structure, and behavior, but they do not typically provide direct insights into an organism's color. While some fossilized impressions may suggest color through mineralization or other means, the original pigments often degrade over time, leaving paleontologists without definitive evidence of the organism's coloration.
Do igneous rocks usually contain fossils?
Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.
Are fossils an important component of igneous rock?
No, fossils are typically found in sedimentary rocks, not igneous rocks. Sedimentary rocks form from the accumulation and compaction of sediments, which can preserve fossils, while igneous rocks form from the cooling and solidification of molten rock, where fossils are usually destroyed.
Why are fossils colored?
Fossils are usually found in sedimentary rock. Sedimentary rock derives its color from a variety of sources, but usually from the minerals which compose the rock.
What rock are fossils are usually found in?
Sedimentary rocks
Are fossils usually found in sedimentary rocks?
yes

Does lamprophyre form fossils?
A lamprophyre is a type of ultramafic intrusive igneous rock. It is very rare for fossils to be formed in igneous rocks (and they usually only form as mold fossils in extrusive deposits). As such fossils will not form in lamprophyres.
What kind of rocks usually have fossils?
The kind of rock is sedimentary.
What sort of places are fossils usually found in?
Sedimentary rock
What type of rock layer are tertiary fossils usually found in?
Tertiary fossils are usually found in sedimentary rock layers. Sedimentary rocks are formed by the accumulation and compression of sediments over time, making them a common host for preserving fossils from the Tertiary period.

WHAT FACTORS TURN FERNS INTO FOSSILS?
Usually volcanic eruptions and age.
Why does petrification usually produce fosssils with more information than fossil casts?
Petrification typically produces fossils with more information because it involves the replacement of organic material with minerals, preserving fine details of the original structure at a microscopic level. This process often retains cellular structures, textures, and chemical compositions, providing a more comprehensive view of the organism's anatomy. In contrast, fossil casts are formed when sediment fills in an impression of an organism, which can lead to the loss of intricate details and contextual information about the original specimen. As a result, petrified fossils offer richer and more informative insights into past life forms.
Do igneous rocks usually contain fossils?
Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.
