These are my fossils from VA river shark teeth, alligator tooth, vertebre, and indian points. Found using floating screen and sifting material of river with shovel. Gray clay deposits are about 120 from ocean in river large scallop and oyster shells are visible on bank and some places have abundant amounts of coral when you dig. River is no more then 30 feet across and in the summer averages only a couple of feet deep. Largest tooth I have found is 3 1/4 inches tip to corner but have seen bigger ones from the area.
