Fossil sites in New York

New York preserves one of the world's most studied Devonian marine sequences. The Hamilton Group across western and central New York is the global reference section for Middle Devonian invertebrates, and Penn Dixie Fossil Park near Buffalo is the easiest place anywhere in the United States to collect a complete trilobite in a single afternoon.

Penn Dixie Fossil Park in Blasdell, just south of Buffalo, is the marquee site. The Hamilton Group shale here produces the trilobite Eldredgeops rana, long known as Phacops rana, along with Greenops, brachiopods, crinoid columnals, horn corals, and pyritised cephalopods. The park is run by the Hamburg Natural History Society as a fee-based collecting site, open roughly April through October. Visitors can keep what they find, and tools are available to borrow.

Beyond Penn Dixie, the Devonian-age Helderberg Escarpment near Albany and the Genesee Gorge in Rochester both expose marine sediments that occasionally produce trilobites, brachiopods, and crinoid material. But these sites are not managed for public collection and require permission from the underlying landowner. Most casual New York fossil hunters drive to Penn Dixie or to the Devonian outcrops along the Mohawk Valley.

Practical notes: the Hamilton Group shale is soft and easy to split with a small hammer and chisel. Eye protection is essential. Plan a half-day for Penn Dixie and check the park's calendar before driving. Special collecting events (Dig with the Experts days) yield deeper layers than the public-access surface piles.

Cross-border options: Penn Dixie is roughly 90 minutes from the Peace Bridge at Fort Erie, putting the Canadian Devonian heartland in easy driving range. Rock Glen Conservation Area near Arkona, Ontario (about 3 hours west of Buffalo) exposes the same Hamilton Group rocks and operates a one-fossil-per-visitor souvenir-collecting policy. The only Canadian site in the marquee set where casual surface collection is permitted. From central New York, Miguasha National Park on Quebec's Gaspé Peninsula (UNESCO Late Devonian fish Lagerstätte) is a long but rewarding two-day drive.

Frequently asked questions

Can you collect fossils in New York?
Penn Dixie Fossil Park charges admission and lets you keep what you find. Other Devonian exposures, such as the Helderberg Escarpment and the Genesee Gorge, are not managed for public collecting and need the landowner's permission. State parks do not allow collecting.
What is New York's state fossil?
The sea scorpion Eurypterus remipes, adopted in 1984. It is a eurypterid, not a trilobite, and it comes from Silurian rocks in the east of the state. The trilobites at Penn Dixie are Devonian and are often mistaken for it.
When is Penn Dixie open?
Roughly April through October. Check the park calendar before you drive, because the Dig with the Experts days reach deeper layers than the public surface piles. Allow half a day, and bring eye protection, because you will split shale.
