Acrotheloidea is an extinct superfamily of discinid brachiopods, that lived from the Early Cambrian to Early Ordovician periods, c. 538 – 471 Ma. They are sometimes alternatively ascribed to the lingulids.
There is evidence for an evolutionary transition through the genera Eoobolus, Pustulobolus, and Bostfordia to the Acrotretids.[2] Acrotheloids have an apical foramen.[3]
