Paleontology and geologyDuring the Triassic, rift basins began to develop in central Maryland as plate movement started to pull apart the supercontinent of Pangea. Sediments washed into these valleys and accumulated as lake and river sediments, represented by layers of red shale, siltstone, and sandstone. Early dinosaurs roamed the landscape, leaving behind mostly footprints. |
