What is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D
Which New York State index fossil may have been present in a rock layer that is missing due to the unconformity?
The trilobite species Eldredgeops rana is a common New York State index fossil found in Devonian rock layers. If a rock layer containing this index fossil is missing due to unconformity, it suggests a gap in the rock record where deposition ceased, erosion occurred, and then new sediment layers were deposited on top.
Removing a fossil from rock is called?
Removing a fossil from rock is called fossil extraction or fossil preparation. This process requires delicate tools and techniques to carefully separate the fossil from the surrounding rock without damaging it.
What are ancient organisms preserved in a rock called?
A fossil is any evidence of an organism preserved in rock.
How can index fossils be used to date rock?
Because if you know how old the fossil is, and you find the fossil inside a rock, you know that rock has a maxium age corresponding with the age of the fossil.
What does fossil?
A fossil is any evidence of ancient life as recorded in rock, including feces, teeth, digestive stones, nests, eggs, bones, tracks, and burrows. ~ fossils provide evidence of the activities of ancient organisms.
What is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D
What is the difference between trace fossil and index fossil?
A trace fossil is one that merely indicates that an organism left evidence of its existence. Some examples would be burrows or footprints that appear in sedimentary rock. An index fossil is of an organism that dates to a particular time in the geologic record, the organism only appearing in a certain segment of that record. Index fossils are indicators of the age of the rock in which they are found.
What is all the information that paleontologists have gathered about past life called?
It's called the fossil record.
Is a sedimentary rock a fossil?
A fossil is any record of an organism preserved in rock, whether it be igneous, sedimentary, or metamorphic. Nearly all fossils are discovered in sedimentary rock.
What does fossilation mean?

What does the rock and fossil record represents?
The history of the Earth and the history of life on Earth.
What is the chronological collection of lifes remains found in layers of rock?
Fossil record
What is umcomformities?
Gaps in the fossil record/ rock layers because of erosion in the soil.
What determines a fossil?
A fossil is simply any evidence of past life that is preserved in rock. That would include trails, footprints, burrows, poop, nests, bones, shells, and any other evidences.
What are trace fossils?
Tracks are an example of a trace fossil
What is the fossil record?
The fossil record is basically the totality of fossils, discovered or undiscovered, and their placement within rock formations and sedimentary layers. The fossil record is important in helping us produce a chronology for the history of life on Earth as well as the evolutionary relationships between the organisms represented by the fossils. The number of fossils we have discovered remains incomplete, which is why we are continuously searching for more.
