Abstract

Twenty-three species of living planktonic foraminifers were examined with a projection X-ray microscope, revealing their internal morphology, wall thickness and surface features without destruction of the shells. Their spatial construction and coiling pattern may be viewed from stereoscopic pairs of radiographs. Measurements of pore concentration and pore diameters were made on shell fragments. X-ray microscopy is particularly helpful in ontogenetic studies of involute species of foraminifers.
