Amygdalodon

Amygdalodon (/əmɪɡˈdælədɒn/; "almond tooth" for its almond shaped teeth) was a genus of herbivorous dinosaur with a long neck. Fossils of the dinosaur have been found in the Toarcian to Aalenian or Bajocian Cerro Carnerero Formation 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 is estimated to have been 12 metres (39 ft) long and 4 metres (13 ft) tall. This quadrupedal dinosaur had an estimated weight of over 5 tonnes (4.9 long tons; 5.5 short tons).[1]  The type species, Amygdalodon patagonicus, was described by Cabrera in Argentina in 1947.[2]
