The Palaeobotanical Society was initiated and organized by Late Prof. Birbal Sahni, F.R.S., with seven other members - Prof. K.N. Kaul, Dr. R.N. Lakhanpal, Dr. S.D. Saksena, Dr. R.V. Sitholey, Dr. K.

    On 10th September, 1946 the Governing Body of the Society resolved that an Institute for research in Palaeobotany be established and Prof. Birbal Sahni was appointed as the first Director of the Institute in an honorary capacity. The foundation stone for the new building of the Institute was laid by Pt. Jawaharlal Nehru, Prime Minister of India on 3rd April, 1949. After the demise of Prof. Sahni on 10th April, 1949, Prof. M. R. Siddiqui proposed at the meeting of the Governing Body of the Society held on 28th October, 1949 that the Institute of Palaeobotany be renamed as "Birbal Sahni Institute of Palaeobotany" in honour of its illustrious founder. The new building of the Institute was opened by Pt. Jawaharlal Nehru, Prime Minister of India, on 3rd January, 1953. The Society continued to develop the Institute till 1969.

     In its meeting held on 25th August 1969, the Society authorized its Governing Body to direct the Trustees to transfer the Birbal Sahni Institute of Palaeobotany and its assets to a new Society, "Birbal Sahni Institute of Palaeobotany Society". This transfer was completed on 12th November, 1969. In December, 1969, the Society reconstituted itself as a professional body and decided to start a journal "GEOPHYTOLOGY" which commenced publication in 1971.
