Description

''Sinokannemeyeria'' was about in length and 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. 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. Compared to ''
