A dinosaur track is a what?

Question

That dinosaur track is a special kind of mold.

Answer 1

It is an indentation in mud from where dinosaurs walked. Typically that mud has turned to stone in the millions of years since it was made. Sometimes a later layer of mud has filled in the dent in the stone and turned to stone so when that top layer is lifted off it has the shape of the foot that made the track.

There is a dinosaur museum in Connecticut that shows a lot of tracks and that lets you bring Plaster of Paris to make your own imprints from those fossilized tracks.

Answer 2

It is a trace fossil, specifically, and the answer you are looking for is that it is an "external mold."

When the inside of a shelled animal (like a clam or snail) gets filled with sediment and turns to rock, producing a replica of the morphology of the inside of the shell, we call it an internal mold. Similarly, if the shell is surrounded in sediment that turns to rock, it will have the shape of the outside of the shell preserved, and is thus called an external mold (and is similar to a dinosaur track in that the track is preserving the outside of the dinosaur's foot). Lastly, if the shell gets destroyed and the external mold later gets filled in with new sediment it will produce a replica of the shell which we refer to as a "cast."
