Fossils, Rocks, Misc Slag? Found along Potomac River near Mallows Bay.
I look for shark teeth along the Potomac fairly often and will pick up other miscellaneous stuff that seems interesting or neat. They're all kind of a very dark brown with warm reddish undertones. Most are between 1/2"- 1" in length except the one in pictures 3&4 which is about 3" long.
