There are not many people who can say they truly love their work, but Mark Renz (a third generation SW Florida native) and his wife Marisa are passionate about theirs. Mark and Marisa started Fossil Expeditions in the early 1990s when there were no other Florida river guide services operating. Mark is the author of several fossil-related books. Marisa is the love of Mark's life, plus artist extra-ordinaire for the books. It's her sweet voice you're likely to hear when calling about trips.
Megalodon Expeditions Featured on the Travel Channel
The Travel Channel's crew hung out with us for a Cash and Treasures feature two years in a row. They were fun, professional, and did a fantastic job. While their program covers the monetary value of fossils, we encourage you to consider the scientific value first. In other words, if your find may be of benefit to science please consider donating it to the appropriate museum. Then everyone benefits!
