Dr. Gordon Hubbell has perhaps the largest and best preserved collection of rare shark jaws and rare fossil shark teeth, and associated teeth, in the world. Dr. Hubbell is considered by many to be one of the world's foremost experts in shark paleontology, and yet he doesn’t even have a degree in paleontology. Dr. Hubbell is a trained veterinarian and therefore, technically, an “amateur” paleontologist. But many still defer to his expertise. His most remarkable possession is a fossilized skull of a white shark, estimated to be a 5-million- year-old specimen.
