Doedicurus are not only well armored, they are huge. These are ancient relatives of the armadillo, yet they weigh almost three times as much!
— Allen, about Doedicurus

Doedicurus ("Pestle Tail") was a prehistoric animal and was also the largest armoured Glyptodont mammal of all time.



Doedicurus lived in South America during the Late Pleistocene period over 1 million years ago.


Doedicurus was a spiky–tailed relative of armadillos–the size of a car. These creatures were not only well–armored, they were also huge. Doedicurus are ancient relatives of the armadillo, except they weighed almost 300 times as much. Their spiked tail clubs alone weighed 40 kilos – as much as a cannonball.


Although fearsome defensive weapons, the Males mostly used their tails on each other to batter rivals into submission during hormone–fuelled jousts for a mate.
