After the work done by Gorjanović-Kramberger, during the sixties, a more detailed stratisgraphical analysis of the site and designations of the cultural and faunistycal remains was undertaken (Malez, 1970a; 1970b; 1970c). In those works, done during the seventies and eighties, the most noticable are the works and contributions of American researchers, namely F.H.Smith, E. Trinkaus and M.H. Wolpoff . Smith (1976) was the first to do a more complete description of the Krapina collection after Gorjanović, and he also compared it to the Neanderthals of western Europe and the Near East.

Trinkaus (1978.) dealt escpecially with the functional aspects, and Wolpoff (1979.) did some paleodemographic research based on the remains of the teeth. During the last two decades a total inventarisation and catalogisation of the collection has been performed (Trinkaus, 1975; Smith, 1976; Musgrave, 1977; Radovčić et al., 1988). Next to them, some authors (Ullrich, 1978; Russel, 1987; Minugh-Purvis, 1988 and others) performed different paleoanthropological researches which contributed to our knowledge about the Neanderthal man. Even today the collection of the remains of the Krapina proto-human even today draws the attention of numerous paleoanthropologists because of its paleonthological value and a large number of fossil samples.
