The Boneheads are a group of students and adults dedicated to paleontology.  Started in 1999 by High School teachers Scott Clark, Larry Millar, and Marsha Morgan, a small group of students were introduced to this hands-on aspect of science.  Students came from four area High Schools.  Adult club members, Jo Cox and Judie Ostlien, taught preparation and mentored students in the wonders of nature, science, and art.  Lively conversations ranged from philosophical and sublime to the ridiculous.

The club worked on late Cretaceous material from a site near Terlingua, Texas, northwest of Big Bend National Park.  Students learned to recognize, dig, jacket, and haul fossils while camping at the dig site.  After opening the jackets in the preparations lab, they learned to clean, preserve, and cast.  The castings were then prepared and painted for display.

The end result was the first true dinosaur show in Abilene Texas.  The "Dinosaurs of Texas" was held on the second floor of  the Grace Cultural Museum.  It ran from June 7, 2003 through August 2004 and was extremely well attended.
