What are fossilized footprints called?

Preserved footprints, also known as ichnites, are a type of trace fossil and a window into the lives of dinosaurs. They formed in the same way our footprints do when walking on soft ground like mud.

Why are fossilized footprints useful?

Trace fossils are useful for paleontologists because they tell about the activity of ancient organisms. … Paleontologists can also estimate dinosaur gait and speed from some footprint track ways. If the footprints are close together, this might show they were running.

What can we learn from fossil footprints?

Fossil tracks can tell us many things. They can tell us how animals moved, what shape and how big their feet were, and the length of their steps. Some tracks can also provide clues about animal behavior, such as where they looked for food or whether they congregated in groups.
