By some amazing stroke of luck, the Berber guy who rented us the camels had a few fiberglass krayt dragon bones from the Dune Sea. He was using them for roofing material on his straw hut, and we bought 6 pieces from him. These are the three largest pieces we were able to get (the other three are not in the photo).

These bone pieces were actually made of fiberglass and scattered across the desert. The bones are concave so as to form only half of a bone piece, and they come in varying sizes and shapes. All of the bones are painted white on one side, and have a grey color on the other.

The Krayt Dragon skeleton appears in the background as C-3P0 is lost in the Dune Sea. Fortunately, there were still remnants of this skeleton during our visit. It's quite amazing that there are any pieces left 22 years later.

The smaller bone piece pictured above is photographed next to a 3 3/4 inch Luke Skywalker action figure for scale. Note that even for a small bone piece, these props were rather large to give the appearance of an enormous skeleton behind C-3P0.

This next shot gives a close glimpse of the inside of one of these bones props, and the fiberglass composition is more noticeable in this photo.

One of the closeups of C-3P0 in the Dune Sea shots shows a few bone pieces which look almost identical to the one pictured above with all the nooks and crannies.

This piece looks like a vertebrae bone fragment, and many of the pieces in the original skeleton were of this form.
