title: A permian productoid brachiopod: life history.
abstract: Spine arrangements on silicified specimens of Waagenoconcha abichi (Waagen) from the Khisor Range of West Pakistan suggest that the juvenile shell attached itself to a foreign object, and that the adult shell lay on its ventral valve in the substrate, anchored and stabilized by a dense corona of long slender spines around the ventral visceral disc.
