What can a footprint tell about an animal?
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.
What kind of information does an impression of an animal footprint provide?
Trace fossils include footprints, trails, burrows, feeding marks, and resting marks. Trace fossils provide information about the organism that is not revealed by body fossils. Trace fossils are formed when an organism makes a mark in mud or sand.
How do footprints become fossils?
Tracks are best preserved after the sediments they are in become hardened. This is called lithification, and it can occur through compaction of the sediments and/or when sedimentary grains are bound together with mineral cement. When loose sediments become rock, the footprints within them become fossilized.
Why do animals have different footprints?
An animal also has a unique foot, but also each footprint is unique! He or she places a unique footprint down in the sand or substrate each time they move a foot. The imprint of the foot depends on several factors including the type of substrate, the gait, the stride, the pace, and even the weather conditions.
What are the three types of footprints?
Prints are divided into three types: visible, plastic and latent.
- A visible print is a transfer of material from the shoe or tire to the surface.
- A plastic print is a three-dimensional impression left on a soft surface.
- A latent print is one that is not readily visible to the naked eye.

How big was a brontosaurus footprint?
Experts identified the largest dinosaur foot ever found, measuring three feet (one metre) wide, was made by a brachiosaur – one of the largest animals to roam Earth.
Why do we have footprints?
Footprints are a kind of evidence of behavior often called a ‘trace fossil’ – geological evidence of biological activity. Estimates of height, weight, and gait of the humans who made the footprints – which also tells us how many people made the footprints.
What animal has 3 pads on its paws?
In the perisodactyls, horses and donkeys have toes reduced to one while tapirs have three toes on the rear foot and four on the front with the axis of weight on one toe on the front feet.
