英文摘要: Fossils of Orsten-type preservation represented by Skara andPhosphatocopida have been reported from the Cambrian Furongian of Western Hunan, China.Their taxonomy and external morphology are well known, but their internal soft-tissueanatomy has not been revealed yet. With the application of synchrotron radiation X-raytomographic microscopy, here we describe the internal soft-tissue anatomy of anOrsten-type preserved phosphatocopid crustacean assigned to Hesslandonaangustata. The internal organs and tissues of this specimen were collapsedafter death to form a visceral mass situated within the labrum and underneath the sternalcuticle. The visceral mass contains the digestive system, including digestive tract andpossible digestive glands. The digestive tract starts from the mouth, followed...
