Abstract

Examination of a fossil enteropneust, Spartobranchus tenuis (Walcott, 1911), from the Cambrian-period Burgess Shale shows that they looked similar to modern enteropneusts but lived in tubes, like modern pterobranchs; the findings shed light on the common ancestor of enteropneusts and pterobranchs, and hence the origin of chordates.
