Punctaconchus is a genus of microconchid tubeworms. It was the last genus of microconchids, and the only genus to exist beyond the Triassic. Their tubes have large pores (punctae) penetrating the tube wall. Tubes lumen is covered by

ripplemark−like transverse ridges. Punctaconchus occurs in the Middle Jurassic of England, France{{cite journal|author=Vinn, O.|author2=Taylor, P.D.|year=2007|title=Microconchid tubeworms from the Jurassic of England and France|url=http://www.app.pan.pl/article/item/app52-391.html|journal=Acta Palaeontologica Polonica|volume=52|issue=2|pages=391–399|accessdate=2012-11-24}} and Poland.{{Cite journal|last=Zatoń|first=M.|last2=Taylor|first2=P.D.|date=2009-12-31|title=Microconchids (Tentaculita) from the Middle Jurassic of Poland|url=http://www.geology.cz/bulletin/contents/art1167|journal=Bulletin of Geosciences|language=en|pages=653–660|doi=10.3140/bull.geosci.1167|issn=1802-8225|doi-access=free}}
