We are describing a new species of mammal in a paper with some 30 authors. Is the first author automatically the species authority or are all authors, or should t the authors decide who came up with the name and should thus be designated authority? How does that work according to the Code? I can see the authority definition as "the person who first publishes a scientific name in a way that satisfies the criteria of availability", but this doesn't deal with multiple authors. What is the consensus or what are the rules on this?
