When I began my exploration of fossil sharks, I knew next-to-nothing about them. To my delight, I have found that professional shark paleontologists and amateur fossil shark tooth collectors have been uniformly kind and generous in sharing their hard-earned expertise with me. While I assume full responsibility for any errors of fact or interpretation that have survived these experts' attempts at expunging them from my work, I would like to put on record my grateful thanks to the following individuals who were extremely helpful in assembling Explorations in Shark Evolution.

I should also acknowledge the wonderful paleo-recreations by artist Ray Troll, whose inspired graphic eye and marvelous sense of humor continue to be downright inspirational
Super-special thanks to my wife, Anne, who — with patience and good humor — took all my raw text and pictures and converted it into a smoothly functioning website.
To all of you, I express my admiration, appreciation and sincere thanks.
