Amygdalodon (/əmɪɡˈdælədɒn/; "almond tooth" for its almond shaped teeth) was a genus of herbivorous dinosaur with a long neck. The dinosaur itself is from the Toarcian to Aalenian or Bajocian stage of the Jurassic (about 170 million years ago), and only a few bone fragments and teeth have been discovered. Very little is known about it, but it is one of the few Jurassic dinosaurs from South America found thus far.
