Unpublished paper, 'Contributions to the study of the errant annelides [annelids] of the older Palaeozoic rocks' by H [Henry] Alleyne Nicholson

Description

Nicholson endeavours to elucidate the organic remains of annelids, or segmented worms, which are found so commonly in the Palaeozoic rocks, and especially in the Silurian strata of Britain, and which are generally known by the names of 'Fueoids', 'Annelide-burrows', and 'tracks'. After expressing his opinion that the first step towards the study of these fossils lies in the provisional grouping and naming of the more marked forms which are already known to exist, Nicholson proceeds to divide the remains under consideration into two great groups. In the first of these groups are those fossils which are truly the burrows of marine worms, as distinguished from trails and surface tracks. The second group comprises trails and surface tracks, which of necessity never pass below the surface of the bed on which they occur.
