The museum is housed in spacious halls in which the exhibits are arranged and displayed in order to illustrate various aspects of palaeobotany, from a generalized and geological point of view. In the museum, the Foundation Stone of the Institute, casted by Professor Birbal Sahni himself, is unique in its own right. It comprises fossils of different geological ages and collected from several countries, embedded in a marble grit-cement block. A ‘Geological Time Clock’ is another and one of the special attractions of the museum, in which the geological time is contracted within 24 hours. The clock communicates the evolution of life on earth as the day progresses from mid-night, and depicts the gradual events of evolution up to the advent of man, within the stipulated time-scale of 24 hours.
