Did You Know...

As Erliansaurus bellamanus remains were found, they were assigned to a basal position and not as a therizinosaurid. The cladistic analysis performed in 2010 removed them from the basal position to a therizinosauroid.

The holotype specimen was based on the only partial skeleton of Erliansaurus that was found. The left arm of that partial skeleton was preserved exceptionally where almost all parts were intact except for the carpal bones which were missing. However, no skull traces were found among the remains.
