Trace fossils are any evidences that an organism existed, including footprints, trails, burrows, chemical marker, and fossilized dung.
Index fossils are those that are only found in a specific range of geologic time, and are used to quickly determine the age of a sedimentary rock sample.
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.
Index fossils are fossils of organisms that lived for a relatively short period of time but were widespread geographically. By identifying these index fossils in a particular layer of rock, scientists can determine the age of the rock and correlate it with other rock layers containing the same index fossils. This allows for the relative dating of rock layers based on the presence of specific index fossils.
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index 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.
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.

they become trace fossils because they made the prints

Index fossils are used to compare the relative ages of fossils. These are fossils that are known to have lived during a specific time period, helping to date the rock layers in which they are found. By identifying and comparing index fossils, scientists can determine the relative ages of different rock layers and fossils.

coal is not a trace fossil
Indeed: a Trace Fossil is that of a burrow, footprint, coprolite, etc that's not a fossil of the animal itself that left the trace.
a fossil record shows what types of fossils there are
They are called index fossils.
a dinosaur footprint is a trace fossil
