**Deinognatha**

**Deinognatha** (lit. "terrible jaws") are a clade of Synischia.

## Description

A clade of Synischia, Deinognatha first emerged around 4212ma. The first Deinognathans (known today as the Eudeinognathans) were the apex predators within the primitive forests spanning TIRA 292b's supercontinent, and remain the top predators of the surviving woodlands.

Unlike the other branches of Osteopoda, the Deinognathans did not adapt to life on the steppe, as their inflexible skeleton and large size made them ineffective predators in open environments. However, radiations of Deinognatha have come to flourish in semiaquatic and aquatic environments, far more than any other clade of Osteopoda.

### Decline

Like the megalobrachids the deinognathans had been struggling against more derived competition for some time, ever since the original evolution of the onychodonts. While some were able to find a terrestrial niche among them, such as the malleognathans and lestognathans, they were eventually doomed to disappear following the mass extinction. However, by a quirk of fate, one genus of hybognathans survived on Septentria as a lone relict of synischian.

### Branches

* Eudeinognatha: Apex predators within the forests (extinct)
* Odontognatha: Semiaquatic and aquatic species (survived only in Hybognatha)
