How are dinosaur tracks made?
This leaves an indentation in the ground.
Over time the sediment hardens and becomes rock, somewhat in the same way cement hardens. It actually does not even take millions of years.
The parts of the footprint do not always split exactly between the two layers of sediment. It may split too high or too low. This decreases the detail that can be seen and thus the quality of the track. How the rock splits cannot be controlled. This makes tracks in which the rock splits in the perfect location very rare, and thus they cost more.

It
starts with a dinosaur stepping in some mud. This leaves an impression
of the dinosaur's foot in the mud. That's shown by the white area
below this dinosaur's foot. (We did not have a picture of a dinosaur
actually stepping in mud - sorry. Please imagine mud under this
dinosaur's foot.)
A
layer of sediment then flows over the footprint and fills it in,
as shown to the right. The light colored brown is the original mud
with the footprint. The dark brown is the new layer of sediment
that fills in the footprint.
Some
time later a human comes along, digs in the ground and splits the
two layers of sediment. The result is two impressions of the footprint.
There is the impressed track (the lower one) and the raised track
(the upper one).
