how to preserve animal tracks

How are footprints preserved?

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.

What are preserved animal tracks 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. But rather than being washed away, evidence of some of these reptiles' movements has survived for millions of years.

Can footprints be fossils?

Trace fossils include footprints, trails, burrows, feeding marks, and resting marks. ... Trace fossils are formed when an organism makes a mark in mud or sand. The sediment dries and hardens. It is covered by a new layer of sediment.

What can footprints tell us?

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.

Did dinosaurs move in herds?

The most definitive evidence that dinosaurs traveled in groups comes from sequences of fossilized footprints called trackways. Several track sites have now been found that suggest herding behavior in some groups of dinosaurs.

Some examples:

Track: an impression made by a single foot.
Trackway: a number of tracks made during a single trip.

What are the important features in footprints and their significance?

Their size, shape, position and presence of the phalanges mark are highly characteristic and can help in the personal identification.
