An Application of Infra-Red Photography to Palæobotanical Research

Abstract

TRANSFER preparations of fossil plants, particularly those of Carboniferous age, provide the palæobotanist with the plant remains separated from the rock matrix and mounted on a transparent base of Canada balsam or cellulose ester. While many of these fossil remains are translucent and give the investigator the opportunity of studying some of their microscopic features by transmitted light, many are opaque with ordinary types of illumination.
