Micropaleontology: Single-Mounting of Microfossils
Specially fashioned micropipets, mechanically guided in the field of the microscope, have been used by Anderson (5) for making single-grain preparations of various types of microfossils. These are first dispersed in a suitable liquid on an object slide, whereafter a specimen is selected under the microscope, taken up into the pipet, and transferred onto another slide. There, it is then covered with a suitable mounting medium and a cover slip. The technique permits rapid sorting and mounting of various microfossils such as pollen, spores, diatoms, and hystrichospherids. Single mounting of as many as 30 to 40 specimens per hour is possible (6). Semipermanent mounts in glycerol jelly or permanent mounts in Canada balsam may be made. The technique is more rapid and versatile than the widely used fishing operations such as those described by Klaus (137) and Madler (159), or those described by Faegri and Iverson (95) for mounting pollen grains.
