Tom Deméré, Ph.D.

Our region has a natural history that extends back millions of years and encompasses many past physical "stages" and biological "players." Even the slightest glimpse into this dynamic past leaves me with a profound sense of wonder.

As Curator of Paleontology, Dr. Deméré has occupied the Joshua L. Baily, Jr. Chair of Paleontology at the Museum since 1994. Tom's research focuses on the evolutionary history and paleobiology of pinnipeds and cetaceans. He is also keenly interested in the geology and paleontology of southern California and Baja California and has published numerous scientific and popular articles on these subjects.

Tom also serves as Director of PaleoServices, a consulting arm of the BRCC that provides paleontological resource assessment and impact mitigation services to public and private developers. This work has been responsible for the discovery, salvage, and conservation of thousands of significant fossils from construction sites in San Diego, Orange, and Riverside counties.
