Where to Find Fossils in Delaware?

The state of Delaware is a great place for fossil hunting. There are many limestone rock outcroppings and exposed marl pits that create perfect conditions for preserving fossils from ancient life forms. 

Fossils were found here for over 500 million years ago.

There is no one place you can go to find fossils, but there are plenty of public lands in the state where the Bureau of Natural Resources does not require excavation permits for collecting purposes.

In this article, I share a list of places you can start with.

Fossil Collecting Laws in Delaware

The Delaware Department of Natural Resources and Environmental Control (DNREC) has created policies and laws that protect fossils. 

In order to collect fossils, geologists must obtain a permit from DNREC. There are also regulations that apply to fossil dealers, researchers, schools, and institutions.

In order to obtain a fossil collecting permit, the applicant must have a valid hunting license or fishing license dated within one calendar year before the date they intend to go on their collecting trips.


Fossils are essentially the remains of animals, plants, and other organisms from millions of years ago. They may be found buried in rocks or even on the surface of the ground, but they will show signs of their age, usually by becoming petrified through time or by turning into the stone itself. 

Fossils can be collected and enjoyed by children, families, teachers, and even professional fossil collectors who enjoy exploring the world’s history.

Many fossils have been found in Delaware, including many shark teeth, dinosaur teeth, and much more. 

There are both private and public landowners who have fossils exposed on their property. The state permits you to collect fossils by obtaining a free permit from the DNREC. It is important to note that the public has no right to collect fossils from private property.

You can find fossils of trilobites, shark teeth, dinosaur teeth, turtles, and much more in Delaware.

Fossils found in Delaware are often different types of marine fossils. 

There are a variety of shark teeth that have been found, including Megalodon and Carcharocles. Megalodon is an extinct species that lived about 28 to 1.5 million years ago and was the largest shark ever to live on the planet.
