Sometime in the 1940s or ‘50s, a dentist named Dr. Joseph Stamp started forming a tooth-filled concrete block at the corner of Riverside Drive and Lexington Avenue in Elkhart, Indiana.

Legend has it that Stamp created it as a memorial to his childhood German Shepherd, Prince, though none of his descendants know why he filled it with human teeth he pulled from his patients. They guess that it “probably saved him on concrete.”

Stamp’s granddaughter, Susan Howard, states, “He pulled thousands of teeth as a dentist” and preserved them in a barrel of chemicals in his practice’s basement, which “kept the teeth from smelling.”

Stamp, who passed away in 1978 at the age of 88, is described as “eccentric as all get out” by local history museum curator, Paul Thomas. The creepy tooth-filled rock can still be viewed today.
