Dennis Braman

Dennis Braman specializes in palynology, the study of organic-walled microfossils such as plant spores and pollen, algae and fungal spores. In the field, rock samples are collected from shales, mudstones, siltstones, and coals to be processed in a lab. After dissolving the mineral material with acids, the resulting organic residue is concentrated and mounted on glass slides. The slides are then scanned using a microscope so that fossils can be identified. Any 10 to 20 gram sample may contain several thousands of specimens, so these are the most abundant fossils we have in the rocks exposed on the prairies of Western Canada.

Current Research

  • Describing a group of angiosperm pollen called the Triprojectates from the Western Interior Basin. This involves going through all of the material he collected over the last two decades and identifying the pollen.
  • Gathering information about all the terrestrial palynomorphs he's encountered in the past from the basin and describing them.
  • Bringing together taxa that are biostratigraphically useful in the Western Interior Basin and describing when they first appear and when they disappear.
  • Working with other researchers in describing and dating a number of fossil bearing beds.
