Adventure brief
2 Tank Dive (per person)
Hunt fossilized shark teeth and ray plates on a guided two-tank dive in Venice FL’s Boneyard. A five-hour, Divemaster-led trip turns the Gulf seabed into an underwater paleontology lesson.
Off the sugar-sand beaches of Sarasota County, the Boneyard — an underwater fossil bed near Venice and Nokomis, Florida — offers one of the region’s most unusual scuba outings: a guided two-tank fossil dive that unspools Pliocene and Miocene time beneath the Gulf surface. The Adventure Collective lists a five-hour trip that runs two 75-minute bottom-times, with tanks, weights, fossil bags, and a Divemaster in the water to teach fossil-hunting technique and keep the group safe. You drop from the boat into shallow, sandy bottomland pocked with ancient shell beds and bone fragments, working in grid-like sweeps to reveal fossilized shark teeth, rays’ dental plates, and other marine relics that have washed out of the fossil shell matrix.
The substrate here is a mix of shell hash and carbonate concretions formed from Miocene-era sediments; visibility and conditions vary with tides and recent storms, but on a clear day the pale fossils stand out against the buff-colored bottom. This trip suits certified divers who have comfortable buoyancy control and who enjoy close-focus searching rather than long glide dives. The pace is deliberate—your Divemaster guides each pass, helps identify finds, and points out other marine life: nurse sharks, grouper, and schools of pogies often cruise nearby, and eagle rays sometimes glide past on shallower edges.
The experience pairs adrenaline—the instant tug of a fossil on your gloved hand—with quiet archaeology: pockets of preserved material that tell a Pleistocene/Pliocene story of Florida’s changing seas. Practical details matter: the tour is based in Nokomis with access to the Venice Boneyard and runs roughly five hours from meet-up to return. Equipment is included for the trip as advertised, but divers should bring personal gear that fits—masks, gloves, and a dive computer make the search easier and safer.
Minimum age is ten. If you’re a diver who loves tactile exploration and the chance to take home a record of deep time, this trip is a rare combination of hands-on discovery and classic Gulf diving. Locally, the Boneyard is a standout because it shifts the focus from reef or wreck diving to palaeontology—Venice has long been known as the “Shark Tooth Capital of the World,” and this guided outing turns a beach hobby into an underwater field lesson.
For visitors staying in Venice or Nokomis, it’s a bucket-list half-day that’s equal parts science and sport. Booking is seasonal; calmer seas in late spring and early fall deliver the best visibility, while summer storms can shorten dives. Operators monitor conditions and adjust the schedule for safety.
Expect small groups and a Divemaster who documents finds and teaches identification. Operator meeting point and boat access are provided after booking. Bring a refillable water bottle and reef-safe sunscreen for surface intervals too.

How many dives and how long underwater?
This is a two-tank trip with each dive up to about 75 minutes or until ~500 PSI, within a five-hour outing.
Is gear included?
The trip description indicates tanks, weights, and fossil bags are included; confirm rental of personal items like masks or computers when booking.
What affects visibility?
Tides, recent storms, and algal blooms influence visibility; late spring and early fall often offer the clearest water.
