Cretaceous Fossils of Delaware
In the late Cretaceous Period, near the end of the age of dinosaurs, Earth’s water level was significantly higher with a large portion of Delaware submerged in the ocean. Scientists determined this underwater area ran roughly south from the Chesapeake and Delaware (C&D) Canal. Over time, sea levels rose and fell in this area, leaving behind sands and clays containing fossilized remains of many creatures living in or near the water. Explore this exhibit to learn more about these fossils found near the C&D Canal in Delaware.
