Debra Baer commented on their own Fossil #011500 7 years, 7 months ago
7 years, 7 months ago7 years, 7 months agoThis was found in beach sand along the coast of Lake Michigan. Is it a denticel from a ray, skate or shark? It would sit on your thumb nail.
Have you learned anything new about this fossil, @debra-baer? Maybe @vperez, @rleder, @lcone, @bkent, @bill-heim, @jnance, @catalina-pimiento, or @dana-ehret have some suggestions based on the image and location information?
