Short summary
<p>In the 1960s-1970s some species of Triassic foraminifera were described as having a planktic mode of life. This was questioned and Malcolm Hart studied the material in Vienna, taking some to London for SEM imaging. Samples collected from Poland are compared to these images and the suggested planktic mode of life discussed. Foraminifera collected in Ogrodzieniec are glauconitic steinkerns with no test material present and none of the diagnostic features needed to determine "new" species.</p>
