Most invertebrates do not fossilize because of the lack of bones or exoskeleton. Soft tissue rarely fossilizes.

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 that fossil record. It includes fossils from all geologic time periods.
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.
The answer is the fossil record :D
Some animal groups with a good fossil record showing their evolutionary development include dinosaurs, mammals, and marine invertebrates like trilobites. Fossil evidence of these groups has allowed scientists to trace their evolutionary history and understand how they diversified and adapted over time.

The fossil record organizes fos- sils by their estimated ages and physical similarities.

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.
The age of the oldest fossil on record is about 3.5 billion years old.
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.
A fossil record is a historical sequence of life indicated by fossils found in layers of Earth's crust.
A palaeorecord is a geological record, especially a fossil record.
The fossil record is incomplete.
The Equus genus first appeared in the fossil record around 4 million years ago during the Pliocene epoch.
