Everyone loves the Tully Monster. This is a mid-body fossil of Tullymonstrum gregarium, a primative jawless fish from the Carboniferous that just happens to be the STATE FOSSIL OF ILLINOIS! This is a pretty good partial specimen. It has a distinct eyebar and a good of the neck. It's about 4 - 5 inches long.
