EVIDENCE OF PRIAPULID SCAVENGING FROM THE EARLY CAMBRIAN CHENGJIANG DEPOSITS, SOUTHERN CHINA

¹ Department of Geology and State Key Laboratory of Continental Dynamics, Northwest University, Xi'an 710069, China elihanj{at}nwu.edu.cn

A Laojieella specimen of the Lower Cambrian Chengjiang Lagerstätte in Yunnan Province, southern China, contains a tubular organism inside its digestive tract. The gut content appears to resemble Archotuba conoidalis, a sessile animal generally regarded as being closely related to cnidarians. This example demonstrates that Laojieella might be a scavenger. Reasons for the extreme paucity of recognizable remains in gut contents are discussed. Such fossils offer new insights into the reconstruction of the complex food web of the benthic community of the Chengjiang fauna.
