Toward an Understanding of the Reproductive Biology of Fossil Plants
During the last several years there has been an increased emphasis in several areas of paleobotany that have focused on the reproductive biology of fossil plants. Several factors have played an important role in stimulating research along these lines. The present paper demonstrates several examples by which the reproductive parameters of fossil plants may be investigated. The total analysis of fossil plant reproductive systems not only provides an additional dimension for comparative studies with closely related extant forms, but moreover allows an opportunity to investigate and more accurately define heretofore abstract concepts concerning the evolution of certain reproductive systems.
