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.

Amygdalodon was 12 meters (50 feet) long, 4 meters (12 feet) tall. This quadrupedal dinosaur was very large, weighing over 5 tons.[1] The type species, Amygdalodon patagonicus, was described by Cabrera in Argentina in 1947.[2]
