1 page.-- Fifteenth Annual Conference of the European Cetacean Society, Rome, Italy, 6-10 May 2001 A total of 673 cornmon dolphins (Delphinus delphis), 82 striped dolphins (Stenella coeruleoalba), and 101 harbour porpoises (Phocoena phocoena) were found stranded along the Galician coast between 1990 and 1999. Tooth samples from 108 cornmon dolphins, 17 striped dolphins and 16 harbour porpoises were analysed for ageing studies. Methods for these purposes were adapted from Hohn & Locþer (199s). Teeth were cleaned with a 5% pepsin solution and then soaked in the decalcifying agent RDO. Sections were cut at 20 mm using a freezing microtome. Optimum sections were selected from each tooth for counting annual rings No
