Holmes, a long time student of Bob Carroll's, received his PhD from McGill
University in 1982. He serves as Research Associate at both the Redpath Museum
and the Canadian Museum of Nature when he is not haranguing his ecological
technology students (Vanier College, Montreal) from the other side of a beaver
pond. Although he has spent some time pondering ceratopsians, he is also
interested in mosasaurs, Palaeozoic tetrapods, and practically everything else
except teleosts, which he is happy to leave to his wife, Alison Murray.
