| 説明 | Seen here we have started to encase the dinosaur footprints in what is known as a field jacket. A field jacket is much like a cast that a doctor would place on a broken arm or leg. Our field jacket consisted of many layers of burlap soaked in plaster-of-Paris into which we also laminate metal pipes to act like splints for additional support. Here Michael is working to remove the very hard sandstone layer below the iron-rich clay layer in which the prints were preserved.
