The Unidentified Therizinosaur Hybrid was a hybrid created by InGen using a species of Therizinosaur and an unknown number of other organisms.
This was one of the hybrids seen on the screen in the Hammond Creation Lab, alongside Stegoceratops and an Unidentified Pachycephalosaur Hybrid. It is unknown if it was ever created. The hybrid seems to have an Amargasaurus-like spine on its neck, which might indicate that it has DNA from the sauropod. It has a gular pouch on its throat that is from an unknown organism.
- Only the front half of this hybrid is shown, as the rest of it is obstructed by a transition to the Indominus rex.
