15 Fossil Hunting Locations In The US
Fossil hunting is one of the few outdoor hobbies where a good afternoon can hand you something 400 million years old. The United States is full of places to do it, but the rules matter as much as the rocks. Never collect on private land without the owner's permission, and never take anything from national parks or federal land, where collecting is prohibited. State and local rules vary widely and are often site-specific, so check before you dig. With that settled, here are 15 spots across the country where the fossils are real, accessible, and waiting.
Potomac River, Maryland (Paleocene; Shark Teeth)

The cliffs along the Potomac south of Washington, DC, are made of fossil-bearing formations, and you do not have to scale them to collect. Comb the gravel along the shoreline and you can turn up shells and Paleocene shark teeth washed down from the cliff faces above.
Nearby Laurel Dinosaur Park was once known for dinosaur eggs and other Cretaceous finds. Anything discovered there now belongs to the park and is sent to the Smithsonian Institution for verification; if a find proves significant, the finder's name goes on the museum label. Public access is mostly interpretive displays and information panels rather than open digging, so set expectations accordingly.
Ambridge, Pennsylvania (Carboniferous; Plants)
The hillsides around Pittsburgh are thick with Carboniferous plant fossils, especially prehistoric ferns. The Ambridge site is a cliff face of loose shale and scree under 100 feet high, so there is no climbing involved, and the rock splits readily to reveal impressions. A pick or a flat screwdriver is about all the equipment you need. Two cautions: the spot sits close to a busy road and offers nothing but the collecting itself, so it is not suited to small children or anyone expecting a park.
Calvert Cliffs, Maryland (Miocene; Shark Teeth)

The Calvert Cliffs are one of the longest stretches of exposed Miocene marine sediment in the world, running more than 24 miles along the western shore of the Chesapeake Bay. The signature find is fossil shark teeth, abundant enough that a patient visitor usually goes home with a few. They make good little keepsakes and pendants even if they carry no resale value.
The catch is access. Much of the cliff frontage is now private property, so the easiest legal collecting is at designated public points like Calvert Cliffs State Park and Brownie's Beach, where you sift the sand and gravel at the waterline rather than disturbing the cliffs themselves, which are unstable and off-limits to digging.
Purse State Park, Maryland (Paleocene; Shark Teeth)
Purse State Park, part of the Nanjemoy Wildlife Management Area along the Potomac, is another beachcombing spot for shells, shark teeth, and ray plates. A fine-mesh net or colander helps: scoop the sand and gravel right at the waterline and let the water do the sorting. Among the more sought-after finds are small Paleocene shells worth learning to recognize before you go. The park has no facilities, so bring your own food and water, but admission is free, access is easy, and crowds are rare.
Westmoreland State Park, Virginia (Miocene; Shark Teeth)
Another Potomac-side location, Westmoreland State Park rewards a full day, with hiking, swimming, and camping alongside the fossil hunting. For collecting, take the park's Beach Trail from the visitor center down to the river and search the sand and pebbles along the shore. The big draw is fossil shark teeth, including the occasional tooth from the giant Megalodon, which once cruised these waters when the region was a shallow sea. The same Miocene layers yield fossils of early whales, dolphins, fish, and shells.
Western New York (Devonian; Trilobites)

The creeks and shale exposures near Buffalo are rich in Devonian marine fossils, above all trilobites and brachiopods, preserved in mudstones and shales. The open creekside sites are not ideal for small children, though a family-friendly park sits nearby (see below). Eighteen Mile Creek and the Lake Erie cliffs are other productive areas, but the cliffs are private property, so stick to combing the fallen rock and respect any no-trespassing signs.
Penn Dixie, New York (Devonian; Trilobites)

Penn Dixie Fossil Park in Hamburg, just south of Buffalo, sits on a former cement quarry and is one of the best-known fossil parks in the country. Its fossils come from the Middle Devonian, around 380 million years old, when western New York lay beneath a warm, shallow sea near the equator. Alongside its famous Eldredgeops trilobites you can find crinoids, brachiopods, corals, snails, and the occasional bit of later petrified wood.
The park charges a modest entry fee, lets visitors keep what they find, and runs guided "Dig with the Experts" events where staff expose fresh material and paleontologists explain the finds. Check the current season and hours before visiting, as access is limited to set days.
Lost River, West Virginia (Devonian; Trilobites)
Near Wardensville, a roadside quarry exposes a Devonian reef around 390 million years old. You will see eager hunters scaling the cliff, but there is no need: plenty of material collects at the base. The fossils here are fragile and the loose shale slides easily, so this is not a site for children. Bring basic tools, a chisel, a shale splitter, and eye protection, and work the scree rather than the cliff.
Aurora, North Carolina (Miocene to Pliocene; Shark Teeth)

Aurora was once a phosphate-mining town where collectors hunted the pits directly. The mine is closed to the public now, but its tailings are trucked to the Aurora Fossil Museum, which maintains a large outdoor pile, essentially a giant sandbox, where anyone can sift for free. Shark teeth are the common reward, including small Megalodon teeth, though because the material is crushed mine waste, large intact fossils are unlikely. It is one of the safest and most family-friendly spots on this list.
Big Brook Park, New Jersey (Cretaceous; Shark Teeth)

New Jersey has a deep Cretaceous pedigree: the Hadrosaurus foulkii unearthed in Haddonfield in 1858 was the first nearly complete dinosaur skeleton found anywhere in the world, the discovery that helped turn paleontology into a real science. You will not match that at Big Brook, but the stream banks here erode out a steady supply of Cretaceous marine fossils. Walk the streambed and pick finds from the rubble rather than digging: shark teeth, ray and fish remains, the occasional Mosasaur tooth or bone, plus shells and belemnites. Expect to get muddy.
Caesar Creek, Ohio (Ordovician; Brachiopods)

The emergency spillway at Caesar Creek State Park, near Waynesville, exposes acres of Ordovician seafloor roughly 445 million years old, packed with brachiopods, crinoids, trilobites, and corals. Collecting is allowed only in the spillway and requires a free permit from the visitor center, which comes with a helpful fossil-identification pamphlet. The rules are simple: no commercial collecting, no tools, no breaking rocks, and you keep only what fits in the palm of your hand.
Because there is no digging, it is an excellent family site. The spillway is flat and open, the fossils are everywhere, and early spring is the best time, after a winter of freezing and thawing has cracked open fresh rock.
Sylvania, Ohio (Devonian; Trilobites)
The Silica Formation of northwest Ohio preserves a Devonian seafloor from about 375 million years ago, and it does so beautifully: the fossils here rank among the best-preserved Devonian marine specimens in the world. Early fish, corals, brachiopods, and echinoderms dominate, many of them lodged in soft shale that releases the fossil with little effort. The material turns up in the shales, limestones, and mudstones of area cement and rock quarries, which makes Sylvania a prized destination for serious collectors.
Peace River, Florida (Miocene to Pleistocene; Ice Age Mammals)

The Peace River is one of Florida's premier Ice Age fossil sites, with mammal remains and abundant shark teeth, Megalodon included, resting in the riverbed. Collecting is done by sifting gravel from the bottom, so you want the water low, around a foot deep, before you go. One legal point matters here: in Florida you can collect shark teeth freely, but any other vertebrate fossil requires a Florida Fossil Permit, a $5 annual permit from the Florida Museum of Natural History, with finds reported back to the museum. Artifacts such as pottery or arrowheads are protected on public land and must be left where they lie.
Venice Beach, Florida (Miocene to Pliocene; Shark Teeth)
Venice bills itself as the shark-tooth capital of the world, and the teeth here are washouts from the same Peace River system. Because shark teeth need no permit, this is an easy, legal, family-friendly hunt. Venice Beach proper is actually poor for it, since the city has trucked in sand to fight erosion and buried the productive layer. Better to use access points south of the Venice jetty, around Casey Key and south of Manasota Key. Small teeth wash up along the surf line; for the larger ones, divers go offshore. A low morning tide after a storm is the ideal time to look.
Bone Valley, Florida (Miocene to Pleistocene; Ice Age Mammals)

Bone Valley, the phosphate district running through Polk, Manatee, Hillsborough, and Hardee counties, is where Florida's larger fossils come from, including rich Ice Age vertebrate deposits exposed by mining. Access is the hard part. Trespassing on a quarry or construction site in Florida is a felony, so the only legal way to dig the phosphate tailings is on an organized field trip with a registered fossil or paleontology club. Join one, and the valley opens up.
Hunting Responsibly
The thread running through every one of these sites is that access and rules vary, and they are the difference between a good day out and a citation. Shark teeth are the friendliest find for beginners, legal almost everywhere and easy to spot, while vertebrate fossils, dinosaur material, and anything on federal land carry real restrictions. Stick to public collecting areas, pay-to-dig parks, and club field trips, get permission for private ground, and leave the national parks alone. Do that, and the fossil record of half a billion years is genuinely open to anyone willing to look down.
