Amygdalodon

Amygdalodon (; "almond tooth" for its almond shaped teeth) is an extinct genus of basal sauropod from the Early Jurassic of Argentina. The type species is Amygdalodon patagonicus. Fossils of Amygdalodon have been found in the Toarcian-aged Cerro Carnerero Formation (about 180-172 million years ago). Very little is known about it, but it is one of the few Jurassic dinosaurs from South America found thus far.
