Endothiodon sp. skeleton



Skeleton of Endothiodon sp. (Broom 1915).

                                                                         
Endothiodon
was a Late Permian dicynodont therapsid from South Africa, dated at about 255 mya. It belonged to the  Class Synapsida, the Order Therapsida, the Suborder Anomodontia, the Infraorder Dicynodontiam and the Family Endothiodontidae.    

Endothiodon was first  described by Owen (1879) for the Karoo region, with a skull and mandible, including 11 teeth. A partial skeleton was later recovered by Broom (1915) at Beaufort West in South Africa, from the Hoedemaker member of Middle Teekloof Formation, dating from the Late Permian Tatarian Age.

In the last century, Endothiodon has been discovered to be distributed throughout the southern hemisphere in the ancient Gondowana continent. It has also been found in Tanzania (Haughton 1932), Zambia (Mazin and King 1991), Mozambique (King 1992), India (Kutty 1972), and Brazil (Boos et al. 2013). 

The  Endothiodon find in Brazil is noteworthy as the first dicynodont to be reported for the Permian of South America. A partial skull and associated lower jaw were discovered in the 1970s in a railway cut at Serra do Cadeado, in the Rio do Rasto Formation of Parana State in Brazil (Barbarena and Araujo 1985).
