Deinognatha

* **Synischia** (lit. "fused hips") are one of two branches of Osteopoda, notable for their large sizes. After the mass extinction, almost all of them went extinct except for only one lineage of Hybognathan in the island of Septentria.

## Description

The defining trait of Synischia is their single fused limb girdle. This grants them larger potential sizes at the cost of speed. As one might expect, Synischians were generally the largest animals to be found in their respective biomes.

Terrestrial Synischians have a single claw on each of their legs, although aquatic species have since discarded them.

### Decline

Due to their specializations for size above all else, the synischians had been losing ground to other clades of osteopods ever since the diversification of the titanopods, even while they continued to diversify. The emergence of the steppe forced the deinognathans into decline. The titanopods in particular suffered heavily from the arrival of more derived leptopod competition in the form of the allobrachids as well as having suffered heavy losses during the first ice age. This overtime ultimately contributed to the decline becoming so steep that by the time mass extinction had begun, most of the synischians, even the less specialized forms, were doomed to extinction. However, through a quirk of fate, a single genus of hybognathans survived in the waterways of Septentria, though the means that facilitated this survival are unclear. Regardless, they are the last remanent of the once mighty synischians, a relict of a major clade of osteopods lost to time.
