Although major collections are not too far away (Carnegie Museum: 3.5 hours; Smithsonian Institution and Field Museum: 7 hours), we have attempted to assemble an adequate research collection of both dinosaur skull casts and modern amniote specimens. The extant collections are part of the registered Ohio University Vertebrate Collections (OUVC).
