The first new permanent exhibit to open after 1964 was the Hall 
of Evolution. Conceived, designed, and fabricated by Museum staff, 
this exhibit opened in 1966 after over two years of planning. It featured 
fossils, specimens, reproductions, and models in a format that presented 
a synopsis of the process of evolution. Other permanent exhibits that 
opened or were developed before 1971 included an outdoor diorama 
with steel-and-fiberglass life-sized models of Tyrannosaurus rex and 
Triceratops; the Davis Hall of Miniatures, which featured pieces from 
the J. Lionberger Davis Collection; and the Egyptian Hall, which gave 
Museum visitors a chance to study ancient artifacts, a reproduction of 
an Egyptian tomb interior, and an Eighteenth Dynasty mummy bor- 
rowed from Washington University. 
In addition to these permanent exhibits, the Museum developed 
or contracted for numerous temporary and traveling exhibits such as 
‘X-rays of Sea Shells,’’ ‘Handicrafts of the Southwest Indians,”’ *‘Our 
Polluted Environment,”” and ‘‘Moon Rocks.’’!® The Museum also 
developed small exhibits for display in bank lobbies and shopping 
centers. 
Artifacts and specimens from the collections were used in both 
temporary and permanent exhibits and new acquisitions were constant- 
ly being sought and accepted. Among these were a large collection of
