Since the early part of the twentieth century, when local iron mining ceased, very few dinosaur bones have been recovered from Maryland and its environs. This is, for the most part, due to a lack of knowledge about local bones by the general public. In addition, modern excavation methods using large machines have removed workers from close contact with the ground. Two noteworthy but isolated discoveries took place in Washington, D.C. In 1898, some men digging a sewer at First and F Streets, S.E., found the remains of a carnosaur ("Dryptosaurus," or a related species). Workers found a very large legbone from Astrodon, a brachiosaurid, while building the McMillan Water Filtration Plant at First and Channing Streets, N.W. in 1942. There have been other finds at other locations, but much needs to be done. The bones are still here, but few people are looking for them!
