Detailed explanation-1: -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.

Detailed explanation-2: -A trace fossil is a result of animal activity. For example, a dinosaur footprint or an arthropod burrow would be an example of a trace fossil.

Detailed explanation-3: -Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber, petrified wood, coal, hair, oil, and DNA remnants.

Detailed explanation-4: -Dinosaur footprints are analysed in terms of length, width, shape, number of toes and size of the heel impression to reveal the type, but not species, of the dinosaurs that made them. For instance, emus and elephants have very different body shapes and walking styles, so they have different feet.
