What is a component of the fossil record?
dinosaur footprints
How the fossil record indicates a long history of changing life forms.?
The fossil record shows that different species have evolved over time. The fossil record also provides evidence of how a specific organism evolved from earlier species. The fossil record shows that organisms have become more complex over time. It also shows which organisms lived during the same time period, which have a common ancestor, and which have become extinct.
The sum of all the fossils that exist is called the?
The sum of all the fossils that exist is called that fossil record. It includes fossils from all geologic time periods.
Do fossil records help to date fossils?
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.
What is the chronological collection of life's remains found in layers of rock?
The answer is the fossil record :D

What is fossil record?
The fossil record is the information about the fossils found in a particular location.
How are fossil organized in the fossil record?
The fossil record organizes fos- sils by their estimated ages and physical similarities.
How does the fossil record organize fossil?
The fossil record organizes fos- sils by their estimated ages and physical similarities.
What does the fossil record provide for paleontologists?
The fossil record provides nothing good for paleontologists.
Which of the following might describe why the fossil record for invertabrates is fragmentary?
There are many reasons for gaps within the fossil record: -The wearing down of rock and dirt (Also known as erosion) -Earthquakes and volcanos because they mess with the layers of rock -Many living things do not become fossils, leaving no fossils behind, in general. -Many environments on Earth are not good for making fossils. Therefore, you will not see many fosils from those environments.
When did the Equus first appear in the fossil record?
when did the equus frist appear in the fossil record
What kind of animals developed near the end of first era?
Animals without backbones, called invertebrates, developed near the end of the Precambrian. Imprints of jellyfish and marine worms have been found in late Precambrian rocks. Because invertebrates were soft, they weren't easily preserved as fossils. This is one of the reasons why the Precambrian fossil record is so sparse.
What is a record fossil?
A fossil record is a historical sequence of life indicated by fossils found in layers of Earth's crust.
What two major developments helped scientists explain the fossil record?
The principle of fossil succession and the theory of evolution have helped scientists explain the fossil record.
What is a palaeorecord?
A palaeorecord is a geological record, especially a fossil record.
