Fossil record, history of life as documented by fossils, the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock.
The fossil record shows transitional fossils answers questions when pertaining to gaps in the fossil record. - Students will read from a scientific article and respond to the hypothesis with Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent. It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers. The IMF found the production and burning of coal, oil and gas was . in fact, most living fossils that are alive … Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.
These fossils often show signs of damage like teeth marks that can be used to determine old predators on the sea floor.
Figure \(\PageIndex{1}\): Dinosaur footprints: Footprints are examples of trace fossils, which contribute to the fossil record. The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. Fossil Preservation.

The fossil record was incomplete in Darwin's time, but many of the important gaps that existed then have been filled by subsequent paleontological research. Support for punctuated equilibrium is seen in fossil records. According to evolution models for the fossil record, there are three predictions:
Fossil Record Examples Humans.
For example, there is a rich fossil record that shows the evolutionary transitions from horse ancestors to modern horses that document intermediate forms and a gradual adaptation o changing ecosystems.
