Synischia (lit. "fused hips") are one of two branches of Osteopoda, notable for being the largest terrestrial creatures of their time.


The defining trait of Synischia is their single fused limb girdle, granting them massive sizes. They boast the largest animals yet observed (terrestrial or otherwise), with the smallest observed species measuring at 1.5m in height. Their feet are wide, with a single claw on each.

With the exception of the Deinognatha, Synischia are herbivorous.
