Suzanne Justice is pictured at the new permanent Pleistocene exhibit at the Black Laboratory of Archaeology at IUB which contains artifacts never seen before by the public; most were collected and donated by the late Frederick W. (Billy) Ellerbusch, an archaeological hobbyist who became fascinated with the prehistoric culture of Indiana as a schoolboy. He later worked at many site excavations in southern Indiana, including Yankeetown, Crib Mound and Angel Mounds, and he allowed an IU grad student to excavate one of the Mississippian sites on his family’s property in Warrick County. In 1959-60, he helped a team of IU researchers excavate the Cox’s Creek mastodon site in Posey County. While much of the material collected from the site was donated to the Evansville Museum of Art and Science, the mastodon bones in the new exhibit were collected by Ellerbusch, who monitored the Cox’s Creek site for more than 30 years until erosion caused much of the site to be destroyed.
