Temporal range: Early Permian
|Helicoconchus elongatus Wilson et al., 2011 from Lower Permian of Texas.|
Wilson, Yancey and Vinn, 2011
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. The tubes branch in two ways: budding from the tube wall and binary fission. They lived in shallow, normal marine environments.
