A palaeoscolecid worm from the Burgess Shale.

Smith, M.R. (2015) 'A palaeoscolecid worm from the Burgess Shale.', Palaeontology., 58 (6). pp. 45-58.

Abstract

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.
