Description edit

 
Restoration of Sinokannemeyeria

Sinokannemeyeria was about 1.8 metres (5.9 ft) in length and 100 kilograms (220 lb) in weight. It had relatively short, stumpy legs which were held slightly sprawling gait to the sides of its body. The limb girdles were formed into large, heavy plates of bone to support the weight of the wide, heavily built body. Sinokannemeyeria was probably not a fast or agile animal.[3]

The front of the jaw had a small horn-covered beak, and there were two small tusks growing from bulbous projections on the upper jaw. These tusks could have been used to dig up roots.[3] Compared to Kannemeyeria, it had broader snout, smaller temporal fenestrae and lower temporal crests. Sinokannemeyeria may had rather indiscriminately seized and torn vegetation in contrast to the more selective cropping of Kannemeyeria.[4]
