DCist fave philliefan99 would have you believe that all of these fossils can be found in nearby Calvert County, Maryland. Evidence of the mako, lemon, tiger, sand tiger, and hammerhead sharks that once perhaps patrolled the Chesapeake has me thankful for harpoons and oceanic bleaching. One find, though, stretches credulity: ray teeth? Rays have teeth? Don’t they use some kind of bone mesh coffee filter–looking thing in their mouths to eat dot-sized fish-bacteria? Provisionally upgrading threat status of rays while I look into this.
