Amygdalodon (/əmɪɡˈdælədɒn/; "almond tooth" for its almond shaped teeth) was a genus of basal sauropod from the Middle Jurassic of Argentina. The type species is Amygdalodon patagonicus.[1]
Discovery
The type species, Amygdalodon patagonicus, was described by Cabrera in Argentina in 1947.[1] Fossils of Amygdalodon have been found in the Toarcian 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.
Size
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).[2]
Classification
Rauhut (2003) placed Amygdalodon as Eusauropoda incertae sedis based on examination of the type material.[3] Later, a cladistic analysis conducted by Carballido et al. (2010) recovered the genus as a non-eusauropod sauropod.[4] Holwerda and Pol (2018) concurred, recovering Amygdalodon as sister to Isanosaurus.[5]
