Trace Fossils

Sometimes while collecting fossils, we find trace fossils.  These are fossils that show evidence of a living organism that is not the organism itself, but rather tracks or marks made by the movement of the organism.  An example of trace fossils in Texas would be the dinosaur tracks in Glen Rose, Texas.  Below you can see other examples of trace fossil we have found.
