Why would we find only Plant fossils in Baltimore, Harford and Cecil Counties? Two correct answers Information: To the east, much older crystalline rocks across Baltimore, Harford and parts of Cecil Counties do not have fossils, as are similar rocks to the west (Blue Ridge and Middletown Valley). Fossils reappear in rocks in the Hagerstown and Hancock areas, but are from a time much earlier than that of the dinosaurs. No dinosaur remains are known to exist in Maryland west of the Triassic rocks of the Gettysburg and Culpeper Basins. Since these counties are on the fall line, there was erosion and fossils may not have formed, preserving remains of dinosaurs and other fossils. There are no ancient animal fossils. These counties had the right environmental conditions to preserve plant material. dinosaur bones and other fossils were not preserved in sedimentary rock. none of the above
