摘要: Lin, J.-P. & Yuan, J.-L. 2008: Reassessment of the mode life Pagetia Walcott, 1916 (Trilobita: Eodiscidae) based on a cluster intact exuviae from Kaili Formation (Cambrian) Guizhou, China. Lethaia, Vol. 42, pp. 67-73 is most abundant trilobite in (lower to middle Cambrian). During course studying museum collections trilobites (n > 1000), containing 22 pagetiid individuals at various growth stages noted. Specimens record range degree 0 meraspid late holaspid phases. Based relative completeness moults except for missing free cheeks, these specimens are interpreted as that had undergone minimal transport prior burial. If pagetiids pelagic or planktonic living habits previously suggested, it would be difficult explain presence clusters. Therefore, here having benthic after onset phase.
