Helicoconchus

Helicoconchus is a microconchid genus that occurs in the Lower Permian of Texas.

It forms small reef-like bodies of tubes branching from a common origin.

The impunctate tubes are greatly elongated for microconchids and have occasional diaphragms with central pits.

They lived in shallow, normal marine environments.
