Hedbergella sliteri - this specific specimen is the "holotype" for this species. That means it is the reference point for what all members of the species should look like. This specimen was identified by Smithsonian scientist Brian Huber. It was taken from a drill core near Antarctica dating back 71-66 million years ago at a time when the south polar region was much warmer, warm enough for the Antarctic continent to have forests and dinosaurs.
