Caption
This portrait shows the tritylodontid Fossiomanus sinensis (upper right) and the eutriconodontan Jueconodon cheni in burrows; both lived the Early Cretaceous Jehol Biota (about 120 million years ago), northeastern China, and showed convergent skeletal features adapted to fossorial lifestyle.
