Kongqiaoheia

Extinct genus of trilobites

Kongqiaoheia rotundata is an asaphid trilobites of the family Raphiophoridae that lived during the late Caradoc of Inner Mongolia, China. K. rotundata was originally grouped with the so-called Taklamakaniinae, a paraphyletic group of tiny, dwarfed raphiophorids that lived in a deepwater environment in what is now the Tarim Basin, including Pseudampyxina, Nanshanaspis, and Taklamakania. Like these other genera, K. rotundata has only three thoracic segments, probably due to paedomorphic dwarfism: other raphiophorid trilobites have at minimum five thoracic segments.
