What are marine fossils?
fossils are something like a plant or bone preserved in rock, then when the preserved thing finally decays there is an impression left in the rock. marine fossils are marine animals, plants, or shells (basically anything in the water, hence marine) that are now fossils.
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers scientists can learn what?
By comparing fossils in higher sedimentary layers with fossils in lower sedimentary layers, scientists can learn about the relative ages of the fossils. This helps in understanding the sequence of events in Earth's history and the evolutionary relationships between different species.
What are the types of fossils?
molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.
What are remaiins or traces of organisms preserved in rock called?
fossils
What characteristics are most common in sedimentary rock?
Common characteristics of sedimentary rocks include layering (stratification), grains or particles of different sizes and shapes (sedimentary structures), fossils, and the presence of minerals like quartz, calcite, and clay minerals. These rocks are formed from the accumulation of sediments that are typically deposited by water, wind, or ice.
Is the information of fossils a common event?
Fossils occur naturally after many hundreds to millions of years. They are more common under ideal conditions.
Are fossils common in non-sedimentary rocks?
no they are not
What are the most common precambrian fossils are?
stromatolites
What do sharks and fossils have in common?

What is the role of fossils in supporting the theory of common descent?
There have been many fossils of intermediate types discovered that provide strong support for the theory of common descent.
What is a common fossil beginning with 'T'?
Trilobites are common fossils throughout the Paleozoic.
What are Two most common types of fossils?

Are trilobites common fossils?
Yes, they normally are fairly common. Except, It is not so common to find complete ones.
What are two common fossils are found in Pennsylvania?
The Trilobite.
What are two common tools that scientists use when cleaning fossils?

What are the most common types of fossils found in Florida?
The most common four types of fossils are:mold fossils(a fossilized impression made in the substrate - a negative image of the organism)cast fossils(formed when a mold is filled in)trace fossils = ichnofossils(fossilized nests, gastroliths, burrows, footprints, etc.)true form fossils(fossils of the actual animal or animal part).
What makes a good index?
fossils that are common and are found in rare places on earth
