What happened to the Caveman dioramas?

Many generations of adults remember coming to the Museum and being transported back to a time when people were living in caves.  The first of two Neanderthal family dioramas was installed in 1929, in the Hall of Historical Geology which was located on the Museum's 2nd floor. In 1933, the Hall of Prehistoric Man (located on the Museum's Ground Floor) opened with a series of 8 prehistoric scenes. In the early 1970s, the Neanderthal figures were replaced with new ones made by Museum artist Joseph Krstolich.  By 1994, the Hall of the Stone Age of the Old World exhibit had been dismantled because most were considered to be scientifically inaccurate. The Hall had included the Neanderthal Family diorama as well as dioramas depicting Mas d'Azil cave in France (also called Azillian Boar Hunt); Aurignacian Cave Art (Gargas cave, France); Chellean scene in northern France; Neolithic Sun Worship; Solutrean sculptor; Swiss Lake Dwellers; Cap Blanc Rock Shelter and the skeleton of Magdallenian girl.
