Joyce: in addition to the people who did the panel, you should contact Sherri Rawstern at the Dacotah Prairie Museum in Aberdeen, SD (605/626- 7117). They have a "Junior Docent" program that is just fantastic. The other person in SD to contact is Joe Mueller at the Mammoth Site at Hot Springs (605/745-6017). Joe's Junior Paleontologist program is also excellent. Either one or both would be excellent sources of information.
