At the 1970 business meeting of the Paleobotanical Section of the Botanical Society of America the section established a prize for the best paper presented at the Section contributed paper sessions. The intent of the prize was to recognize an outstanding contribution by either a student or a recent Ph.D. If no outstanding paper was given at a meeting, the prize would not be given that year. The prize was named THE PALEOBOTANICAL AWARD, and the `name of the recipient was to be announced at the Section business meeting. The award was to be accompanied by a $100 check from the Botanical Society and by a Botanical Society Banquet ticket. The official announcement of the award and the check were to be presented at the Bot. Soc. banquet. As of 1976, the prize was renamed THE ISABEL COOKSON PALEOBOTANICAL AWARD. As of 1985, poster presentations were also to be eligible for the prize (but see below).


At the 1985 Section business meeting, the amount of the award was increased to $300, and criteria for eligibility were clarified and revised. Eligibility is to be limited to current students and those who recently have received their Ph.D. (that is, the work presented in the talk represented their student work). Also, only abstracted papers are to be considered (i.e., poster presentations and informal presentations are not included).

Presentation of Prize

The prize is to be judged by a committee of three members appointed by the Chair of the Section. The prize does not have to be given every year. The Section also buys a B.S.A. banquet ticket for the winner where the prize will be presented.
