Ptychodus mortoni
The shell-crushing shark, Ptychodus mortoni, patrolled the bottom of the Western Interior Seaway for mollusks.
Armed with pavements or batteries of robust, blunt teeth, this strange shark was uniquely capable of preying on the abundant inoceramid bivalves. This specimen is preserved with around 200 teeth.
