My talk at the International Conference on Vertebrate Morphology in Barcelona, Spain on 10 July, 2013, in a symposium on "Morphology: The Great Integration. Contemporary Relevance of an Old Field."
Note: the images in this presentation show dissections of long-dead animals and so may be upsetting or unpleasant to some viewers. No animals were killed for the purpose of dissection. Dissections shown were part of normal postmortem veterinary investigations, with scientific research benefiting from that opportunity as well.
