title: Data from: A palaeoscolecid worm from the Burgess Shale

description: Palaeoscolecid worms are a ubiquitous group of Early Palaeozoic
 ecdysozoans that are curiously lacking in the archetypal Cambrian
 Lagerstätten, the Burgess Shale. Here I describe Scathascolex minor gen.
 et sp. nov, the first unequivocal palaeoscolecid from this site.
 Scathascolex is armoured with simple Hadimopanella-like plates, but lacks
 smaller platelets, pointing to a close affinity with the Palaeoscolecida
 sensu stricto. Neither preservational nor environmental factors account
 for the scarcity of palaeoscolecids in the Burgess Shale, which presumably
 represents an ecological phenomenon.
