Fourteen symposia on early/lower vertebrates have taken place over the last 50 years, usually at about four year
intervals. An average 60 participants have taken part at these symposia, with over one hundred occasionally. The
results of the symposia have been published in proceedings. The symposia started honoring E. A:son Stensiƶ and
E. Jarvik. Honors were taken up at the 11th symposium in Uppsala again. Since the 13th symposium a Stensiƶ
award is also given to young researchers in the field.
