A review of echinoderms from Pleistocene marine deposits near Saint John, New Brunswick

Two species of echinoderm, the brittlestar Ophiura sarsii Lütken and the common green sea urchin Strongylo-centrotus droebachiensis Müller, are found in Pleistocene marine clays near Saint John. Today, both of these echinoderms are considered boreal species and both range from the...
