The specimen was prepared in the field by M. Vremir and final preparation was performed by Amy Davidson at the American Museum of Natural History (AMNH). A preparation record is held in the AMNH Division of Paleontology database. During final preparation, the bone surface was scrubbed with a stiff brush in tap water and remaining matrix scraped off with a carbide needle. Water was used to improve visibility of the cancellous bone when carving off matrix from the epiphysis. Two previous adhesive joins were taken apart, matrix was scraped off the contacts, and the fragments were rejoined with a mixture of 3M Scotchlite glass microballons and Paraloid B-72 (Rohm and Haas Company), an ethyl methacrylate and methyl acrylate copolymer.
