Fossils were systematically collected within a 2.5-meter-thick sequence divided into ten stratigraphic intervals. Each interval represents an induced time-averaged assemblage of various event (obrution) beds of unknown duration. Overall, the different fossil assemblages are taxonomically and ecologically similar, suggesting the presence of a single community type recurring throughout the Mafang section. The Mafang community is dominated by epibenthic vagile hunters or scavengers, sessile suspension feeders, and infaunal vagile hunters or scavengers represented primarily by arthropods, brachiopods, and priapulids, respectively. Most species have low abundance and low occurrence frequencies, whereas a few species are numerically abundant and occur frequently. Overall, in structure and ecology the Mafang community is comparable to the Middle Cambrian (Series 3, Stage 5) Burgess Shale biota (Walcott Quarry, Yoho National Park, British Columbia, Canada). This suggests that, despite variations in species identity within taxonomic and ecological groups, the structure and ecology of Cambrian Burgess Shale-type communities remained relatively stable until at least the Middle Cambrian (Series 3, Stage 5) in subtidal to relatively deep-water offshore settings in siliciclastic soft-substrate environments.\n                  <\/jats:p>","DOI":"10.1666\/12056","type":"journal-article","created":{"date-parts":[[2013,10,14]],"date-time":"2013-10-14T11:44:53Z","timestamp":1381751093000},"page":"50-69","source":"Crossref","is-referenced-by-count":69,"title":["Diversity and species abundance patterns of the Early Cambrian (Series 2, Stage 3) Chengjiang Biota from China"],"prefix":"10.1017","volume":"40","author":[{"given":"Fangchen","family":"Zhao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Bernard","family":"Caron","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David J.","family":"Bottjer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shixue","family":"Hu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zongjun","family":"Yin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maoyan","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2016,4,8]]},"reference":[{"key":"S0094837300001585_ref28","doi-asserted-by":"publisher","DOI":"10.1126\/science.1162794"},{"key":"S0094837300001585_ref15","first-page":"423","article-title":"The community structure of the Middle Cambrian Phyllopod bed (Burgess Shale)","volume":"29","author":"Conway Morris","year":"1986","journal-title":"Palaeontology"},{"key":"S0094837300001585_ref9","doi-asserted-by":"publisher","DOI":"10.1890\/11-1952.1"},{"key":"S0094837300001585_ref39","doi-asserted-by":"publisher","DOI":"10.1666\/0094-8373(2004)030<0325:EOCBMC>2.0.CO;2"},{"key":"S0094837300001585_ref11","doi-asserted-by":"publisher","DOI":"10.1387\/ijdb.072513cj"},{"key":"S0094837300001585_ref18","doi-asserted-by":"publisher","DOI":"10.4202\/app.2008.0110"},{"key":"S0094837300001585_ref43","doi-asserted-by":"publisher","DOI":"10.1038\/nature02648"},{"key":"S0094837300001585_ref44","doi-asserted-by":"publisher","DOI":"10.1016\/j.palaeo.2003.06.001"},{"key":"S0094837300001585_ref25","doi-asserted-by":"publisher","DOI":"10.1186\/1741-7007-11-64"},{"key":"S0094837300001585_ref24","doi-asserted-by":"publisher","DOI":"10.1007\/s11434-005-2151-0"},{"key":"S0094837300001585_ref6","doi-asserted-by":"publisher","DOI":"10.2110\/palo.2003.P05-070R"},{"key":"S0094837300001585_ref48","doi-asserted-by":"publisher","DOI":"10.2110\/palo.2009.p09-004r"},{"key":"S0094837300001585_ref4","volume-title":"The fossils of the Burgess Shale","author":"Briggs","year":"1994"},{"key":"S0094837300001585_ref37","unstructured":"McAleece N. 1999.
