It could reach 3 metres (9.8 ft) in length and a weight up to 1,500 kilograms (3,300 lb)[3] the upper skull and the body were protected by hemispherical armor composed of hundreds of rounded scales. The tail, short and wedge-shaped, consisted of small bony bands with small spikes used for defense. Preserved tracheal rings are known from one specimen.[4]
