**Brachiocephalia**

**Brachiocephalia** (lit. "arm-heads") is a clade of browsing xenodonts.

## Description

Brachiocephalians are heavy, ground-dwelling browsers analogous to megalobrachids on the mainland. They have convergently evolved robust mandibles with flattened teeth for grinding down plant matter, along with a large, multi-chambered foregut to improve digestive efficiency.

Brachiocephalians are one of three lineages of osteopods to develop centaurism, although they are unique in that the trait evolved to improve feeding rather than speed. The hind three pairs of limbs hold the animal's weight, and bear blunt hoof-like claws. The forelimbs, on the other hand, are held permanently off the ground, and are used to help reach for vegetation.

The only catalogued species of brachiocephalian is *Cyanolaimus sahari*.
